Step 1: Understanding the Problem and Initial Setup
Alright guys, first things first. Let's understand what we're dealing with. The expression b^3 / (b^2 - 6b + 9) : b / (b - 3) involves division of algebraic fractions. Remember that dividing by a fraction is the same as multiplying by its reciprocal. So, our first move is to rewrite the division as multiplication. This will make the expression easier to handle. This concept is fundamental in algebra and is used extensively in solving various types of problems. Recognizing this relationship between division and multiplication is key to solving the problem accurately. The original problem is written in a particular format. Let's convert the division symbol into the multiplication of the reciprocal. This allows us to simplify the problem step-by-step using operations and transformations. We need to remember to flip the second fraction to its reciprocal form. This transformation prepares the expression for further simplification by combining the terms. This step is about laying the groundwork for the rest of the simplification process. Remember, in algebra, careful attention to detail is crucial. This helps prevent errors and ensures a smooth solution process. Transforming the expression in this way is the first essential step in our simplification journey.
Let’s start by rewriting the division operation as multiplication by the reciprocal. This simplifies the expression, making it easier to work with. So, our original problem b^3 / (b^2 - 6b + 9) : b / (b - 3) transforms into b^3 / (b^2 - 6b + 9) * (b - 3) / b. This is a crucial step that sets the stage for the simplification process. This sets the stage for the rest of the simplification process. We now have a multiplication problem with two fractions. This transformation is based on the rules of fractions, where division by a fraction is equivalent to multiplying by its reciprocal. In algebra, this is very important. Understanding and applying these rules helps in solving a wide array of problems. By doing so, we are simplifying the expression and setting ourselves up for the next steps. Now that we have the expression in a more workable form, we can move on to the next step, which involves factoring and simplifying.
Step 2: Factoring the Quadratic Expression
Now, let's look at the quadratic expression b^2 - 6b + 9. We need to factor this. Factoring is like finding the building blocks of the quadratic expression. It's essentially breaking it down into two binomials (expressions with two terms). Factoring is a fundamental skill in algebra and is essential for solving many types of problems. When we factor, we are expressing a complex expression as a product of simpler ones. A correctly factored expression makes it much easier to simplify the overall problem. This stage involves the identification of common factors and the application of factoring techniques. The ability to factor quadratic expressions efficiently is crucial for simplifying complex algebraic problems. In this case, we have a quadratic expression and we can notice that the number 9 is a perfect square, and 6b can be divided into 3b and 3b. To factor b^2 - 6b + 9, we need to find two numbers that multiply to 9 and add up to -6. These numbers are -3 and -3. So, the factored form of b^2 - 6b + 9 is (b - 3)(b - 3) or (b - 3)^2.
Let's break that down even further. We're looking for two numbers that, when multiplied together, give us 9 (the constant term) and when added together, give us -6 (the coefficient of the b term). Think of it like a puzzle – we need to find the right pieces. The numbers that fit the bill are -3 and -3. This means we can rewrite the quadratic expression as (b - 3)(b - 3). Another way to look at this is to recognize that b^2 - 6b + 9 is a perfect square trinomial. This means it can be written as (b - 3)^2. The process of factoring transforms the expression into a product of simpler terms, which allows for easier simplification. Factoring helps us reveal the structure of the expression. So, it's easier to identify common factors that can be canceled out in the subsequent steps. This will make the expression much easier to manage. Now, we are ready to rewrite the original expression with the factored form. We are now one step closer to solving our problem.
Step 3: Rewriting and Simplifying the Expression
Now, let’s rewrite the expression with the factored quadratic. Remember our expression transformed to b^3 / (b^2 - 6b + 9) * (b - 3) / b. We now know that b^2 - 6b + 9 is equal to (b - 3)^2. So, we can rewrite the expression as b^3 / (b - 3)^2 * (b - 3) / b. We’ve replaced the quadratic with its factored form. Now that we have the factored form, the expression is ready for simplification. Now, we are going to simplify the expression by canceling out common factors. This step is about removing unnecessary terms to obtain the simplest form of the expression. This makes the overall expression much easier to understand and work with. It's like cleaning up a messy room – removing the clutter to reveal the essentials.
Let's get rid of some of those unnecessary terms. We can cancel out a b from the numerator (b^3) and the denominator (b). This leaves us with b^2 in the numerator. Also, we can cancel one (b - 3) from the numerator and the (b - 3)^2 in the denominator. This process of canceling common factors is the essence of simplification. Now our expression looks much simpler. After canceling, we're left with b^2 / (b - 3). We have successfully simplified the original expression. After canceling, we're left with b^2 / (b - 3). At this point, no further simplification is possible. The expression is in its simplest form. We have successfully simplified the original expression and arrived at our final answer. The ability to simplify these types of expressions is a crucial skill in algebra, as it simplifies calculations and helps in solving equations. The final answer, b^2 / (b - 3), is the simplified form of the original expression. The result is a rational expression that represents the simplified form of the original expression. Simplifying expressions like this is a fundamental skill in algebra and is essential for solving many types of math problems.
