Question

Prove the identity (a+b)(a-b)=a^2-b^2 For each step list the property or definition that justifies the step.

Answer 1

Answer:(a+b)(a-b)=a^2-b^2 are equal

Step-by-step explanation: by expanding

The equation

(a+b)(a-b)

Multiple both

a^2-ab+ab-b^2

Which by collecting like term -ab+ab=0

Making

a^2-b^2
