Question

If (a + b)ka whole square = 2(a square +b square ) then
(a+b=0 , a = b, 2a=b, ab=0)​

Answer 1

Step-by-step explanation:

so what are u asking for ??

Answer 2

Answer:

a=b

Step-by-step explanation:

(a+b)² = 2a² + 2b²

a²+2ab+b² = 2a² + 2b²

2ab = a² + b²

a² -2ab + b² = 0

(a-b)² = 0

taking square root on both sides,

a - b = 0

a = b

Hence, proved.
