Question

(a+b)^2-(a-b)^2
Simplify the following

Answer 1

$\huge\star\bold\red{ANSWER}$

(a+b)²-(a-b)²

Let (a+b)= x

and, (a-b)= y

using identity a²-b²=(a+b)(a-b)

$\star\bold\red{Then}$, (x)²-(y)²=(x+y)(x-y)

$\star\bold\red{Now,}$,substitute with original value

$\star\bold\red{We}$$\bold\red{get,}$ (a+b)²-(a-b)²=[a+b+a-b][a+b-(a-b)]

=> (2a)(2b)

=>4ab $\bold\red{....ans....}$
