Question

If 2(a2+ b2) = (a +b)2 then​

Answer 1

Step-by-step explanation:

Given:

2(a+b)=(a+b)

2a?+ 2b?=(a+b)? Formula used

[ (a+b)? = a? + b?+ 2ab] =

2a?+2b?= a?+ b? + 2ab

2a?- a? +2b? -b² = 2ab

a2+ b?= 2ab

a? + b? - 2ab=0

Formula used [ (a-b)?= a?+ b? - 2ab]

(a-b)2=0

Taking square root on both sides

a-b=0

a = b

Henceproved
