Question

2. If a = b = 2, what is (a2 – b2) + 2ab?​

Answer 1

Given,

a = b = 2

find: (a²-b²) + 2ab

a²-b² = (a+b)(a-b) [identity]

substituting the values,

(a²-b²) + 2ab

(a-b)(a+b) + 2ab

(2-2)(2+2) + 2(2)(2)

0(4) + 8

0 + 8

= 8

Hope it helps

have a great day

GIVEN :---

IF , a=b = 2 , then a^2 - b^2 + 2ab = (? )

Solution : --

$if \: a = b = 2 \: \: so \\ {2}^{2} - {2}^{2} + 2 \times 2 \times 2 \\ = 8.(answer.)$
