Question

Factorize the following algebraic expression :-
1. (x + a)² – (x – a)²​

Answer 1

Answer:

(x+a+x-a) (x+a-x-a) or 2x can be the answer i think the answer should match

Answer 2

To solve ( x+a)^2 we have to use identity (a+b)^2 = a^2+b^2+2ab
X^2 + a^2 + 2xa

To solve (x-a)^2
Identity used = ( a-b )^2 = a^2 + b^2 - 2ab
:-
x^2 + a^2 - 2xa

APQ:-
( x^2 + a^2 + 2xa ) - ( x^2 + a^2 - 2xa )

X^2 + a^2 + 2xa - X^2 - a^2 + 2xa

4xa = ANSWER
