Question

find the product. simplify your answer.
(m + 1)(m - 1)

Explanation:

Step1: Apply the difference of squares formula

The formula for the product of a sum and a difference is \((a + b)(a - b)=a^2 - b^2\). Here, \(a = m\) and \(b = 1\).
So, \((m + 1)(m - 1)=m^2-1^2\)

Step2: Simplify the expression

Since \(1^2 = 1\), we have \(m^2-1\).

Answer:

\(m^2 - 1\)
