Question

17. If 2(a +62) = (a+b)2, then show that a= b​

Answer 1

Answer:

LHS:

=2(a+62)

=2a+142

RHS:

=(a+b)2

=2b+2a

》2a+142=2b+2a

》2a+2a+2b=142

》4a+2b=142

》6ab=142

》ab=142/6

》ab=23.6

:- a=23.6

:- b=23.6

Answer 2

2a+2
The question is not correct
It must be 2(a^2+b^2)=(a+b)^2
Then 2a^2+2b^2=a^2+2ab+b^2
So (a-b)^2=0
And a=b
