Question

If 2(a²+ b²) = (a + b)² then
a. a + b = 0

b. a = b

c. 2a = b

d. ab = 0​

Answer 1

2 (a²+b²) = (a+b)²

2a² + 2b² = a² + 2ab + b² ---------------------------- as (a + b)² = a² + 2ab + b²

2a² - a² + 2b² - b² – 2ab = 0

a² + b² – 2ab = 0 ------------------------- as (a – b)² = a² – 2ab + b²

(a – b)² = 0

a – b = 0

a = b

Hence proved

Answer 2

Answer:

it will be:

(b) a = b
