Question

multiply.
$(x + 10)(x - 10)$
simplify your answer.

Explanation:

Step1: Apply the difference of squares formula

The formula for the product of the sum and difference of two terms is \((a + b)(a - b)=a^2 - b^2\). Here, \(a = x\) and \(b = 10\). So we have \((x + 10)(x - 10)=x^2-10^2\).

Step2: Calculate \(10^2\)

We know that \(10^2 = 100\). Substituting this back, we get \(x^2 - 100\).

Answer:

\(x^2 - 100\)
