Answer:
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>tips and formulas:</h3>
- algebraic identity:(a-b)²=(a+b)²-4ab
<h3>let's solve:</h3>
therefore
using the identity our answer is (a-b)²
let's prove it
- (a-b)²:a²-2ab+b²
- rewrite -2ab as 2ab-4ab:a²+b²+2ab-4ab
- use (a+b)²=a²+2ab+c²:(a+b)²-4ab
therefore
we have also proven that
