Question

find the product. simplify your answer.
(h + 2)(h - 2)

Explanation:

Step1: Apply the difference of squares formula

The formula for the difference of squares is \((a + b)(a - b)=a^2 - b^2\). Here, \(a = h\) and \(b = 2\).
So, \((h + 2)(h - 2)=h^2-2^2\)

Step2: Calculate \(2^2\)

\(2^2 = 4\), so substituting back we get \(h^2 - 4\)

Answer:

\(h^2 - 4\)
