Question

multiply.
(5 + 3x)(5 - 3x)
simplify your answer.

Explanation:

Step1: Apply difference of squares formula

The expression \((a + b)(a - b)\) can be simplified using the difference of squares formula \(a^2 - b^2\). Here, \(a = 5\) and \(b = 3x\).
So, \((5 + 3x)(5 - 3x)=5^2-(3x)^2\)

Step2: Calculate the squares

Calculate \(5^2 = 25\) and \((3x)^2 = 9x^2\).
Substituting these values back, we get \(25 - 9x^2\)

Answer:

\(25 - 9x^2\)
