Question

Simplify: (2 + 5)
2 − (2 − 5)
2 using identities
step by step

Answer 1

Answer:

(2+5)²-(2-5)²[in this we will use identity of the following expression which is Identity(III)— (x)²-(y)²=(x+y)(x-y)] so we will apply it

(2+5)²-(2-5)²=[{(2+5)+(2-5)}{(2+5)-(2-5)}]

[{(2+5)+(2-5)}{(2+5)-(2-5)}]=[{7-3}{7+3}]

[{7-3}{7+3}]=4*10=40

Simplify: (2 + 5)

2 − (2 − 5)

2 using identities

step by step answer is 40
