Question

multiply.
(v + 5)(v - 5)
simplify your answer.

Explanation:

Step1: Identify the formula

This is a difference of squares: \((a + b)(a - b) = a^2 - b^2\). Here, \(a = v\), \(b = 5\).

Step2: Apply the formula

Substitute \(a = v\) and \(b = 5\) into the formula: \(v^2 - 5^2\).

Step3: Simplify \(5^2\)

\(5^2 = 25\), so the expression becomes \(v^2 - 25\).

Answer:

\(v^2 - 25\)
