Question

For what values of a and b would (a+b)^2 = a^2 + b^2 ? Prove your answer

Answer 1

when ab =0 ,,the above will hold true..

Answer 2

i.e. either a=0 or b=0 or both =0

Answer 3

just expand (a+b)^2 and you should get your ans.

Answer 4

f(a or b) = a^2 + b^2

Only x = 0 would prove this.

f(0) = 0^2 + 0^2
f(0) = 0

Answer 5

I mean a or b = 0, not x = 0
