Question

What is (a+b) (a-b)? (explain)

Answer 1

Answer:

a+b a-b is a property which is a2-b2

Answer 2

Step-by-step explanation:

it's a formula used for expanding

for eg. expand (13+x)(13-x)

use this formula.... so for us

(a+b)(a-b) = a² and b²

so 13 is our a and x is our b

by this formula

(13)² (x)²

is the answer and now we will simplify it

13² = 169

Final answer - 169-x²
