Introduction

In algebra, factorizing expressions is a crucial concept that helps us simplify complex equations and solve for unknown variables. In this article, we will focus on factorizing the expression $(w - 12)(w - 5) = 0$ and find the values of $w$ that satisfy this equation.

What is Factorizing?

Factorizing is the process of expressing an algebraic expression as a product of simpler expressions, called factors. These factors can be numbers, variables, or a combination of both. The goal of factorizing is to break down a complex expression into smaller, more manageable parts that can be easily solved or manipulated.

The Expression to be Factorized

The given expression is $(w - 12)(w - 5) = 0$ . This expression consists of two binomial factors, $(w - 12)$ and $(w - 5)$ , which are multiplied together to form a quadratic expression.

Step 1: Apply the Zero Product Property

The zero product property states that if the product of two or more factors is equal to zero, then at least one of the factors must be equal to zero. In this case, we have:

(w - 12)(w - 5) = 0

Using the zero product property, we can set each factor equal to zero and solve for $w$ :

(w - 12) = 0 \quad \text{or} \quad (w - 5) = 0

Step 2: Solve for $w$

Now, we need to solve each equation for $w$ :

(w - 12) = 0 \quad \Rightarrow \quad w = 12

(w - 5) = 0 \quad \Rightarrow \quad w = 5

Therefore, the values of $w$ that satisfy the given equation are $w = 12$ or $w = 5$ .

Conclusion

In this article, we factorized the expression $(w - 12)(w - 5) = 0$ and found the values of $w$ that satisfy this equation. We applied the zero product property to break down the expression into simpler factors and then solved each equation for $w$ . The final answer is $w = 12$ or $w = 5$ .
