Introduction

Factorizing expressions is a fundamental concept in algebra that involves breaking down complex expressions into simpler ones. It is a crucial skill that helps in solving equations, simplifying expressions, and understanding the underlying structure of mathematical problems. In this article, we will focus on factorizing two given expressions: $\frac{(x-1)^2}{(1-x)^2} = 1$ and $43a(a^2 + 4ab + 8b^2)$ . We will delve into the step-by-step process of factorizing these expressions and provide a comprehensive understanding of the underlying concepts.

Factorizing the First Expression

The first expression is $\frac{(x-1)^2}{(1-x)^2} = 1$ . To factorize this expression, we need to simplify it by canceling out common factors.

Step 1: Simplify the Expression

The given expression can be simplified by canceling out the common factors in the numerator and denominator.

$\frac{(x-1)^2}{(1-x)^2} = \frac{(x-1)(x-1)}{(1-x)(1-x)}$

Step 2: Factorize the Numerator and Denominator

Now, we can factorize the numerator and denominator separately.

$\frac{(x-1)(x-1)}{(1-x)(1-x)} = \frac{(x-1)^2}{(1-x)^2}$

Step 3: Cancel Out Common Factors

We can cancel out the common factors in the numerator and denominator.

$\frac{(x-1)^2}{(1-x)^2} = \frac{(x-1)(x-1)}{(1-x)(1-x)}$

Step 4: Simplify the Expression

After canceling out the common factors, we are left with a simplified expression.

$\frac{(x-1)(x-1)}{(1-x)(1-x)} = 1$

Conclusion

The factorized form of the first expression is $1$ . This means that the expression is already in its simplest form, and no further factorization is possible.

Factorizing the Second Expression

The second expression is $43a(a^2 + 4ab + 8b^2)$ . To factorize this expression, we need to identify the common factors and group them together.

Step 1: Identify Common Factors

The common factor in the expression is $a$ . We can factorize the expression by grouping the terms together.

$43a(a^2 + 4ab + 8b^2) = 43a(a(a + 4b) + 8b^2)$

Step 2: Factorize the Expression

Now, we can factorize the expression by grouping the terms together.

$43a(a(a + 4b) + 8b^2) = 43a(a(a + 4b) + 2^3b^2)$

Step 3: Factorize the Expression Further

We can factorize the expression further by grouping the terms together.

$43a(a(a + 4b) + 2^3b^2) = 43a(a(a + 2b) + 2b(a + 2b))$

Step 4: Factorize the Expression Completely

After grouping the terms together, we can factorize the expression completely.

$43a(a(a + 2b) + 2b(a + 2b)) = 43a(a + 2b)(a + 2b)$

Conclusion

The factorized form of the second expression is $43a(a + 2b)(a + 2b)$ . This means that the expression has been broken down into its simplest form, and no further factorization is possible.

Conclusion

$In conclusion, factorizing expressions is a crucial skill that helps in solving equations, simplifying expressions, and understanding the underlying structure of mathematical problems.
