Question

multiply.
(8 + d)(8 - d)
simplify your answer.

Explanation:

Step1: Identify the formula

This is a product of a sum and a difference, which follows the formula \((a + b)(a - b)=a^2 - b^2\). Here, \(a = 8\) and \(b = d\).

Step2: Apply the formula

Substitute \(a = 8\) and \(b = d\) into the formula: \((8 + d)(8 - d)=8^2 - d^2\).

Step3: Calculate \(8^2\)

\(8^2=64\), so the expression becomes \(64 - d^2\).

Answer:

\(64 - d^2\)
