Question

If a-b=b and a+b=8 find a2+b2​

Answer 1

Answer:

We have,

a−b=7               …… (1)

ab=8                   …….. (2)

On squaring both sides of equation (1), we get

(a−b)  

2

=(7)

a  

2

+b  

2

−2ab=49

From equation (2), we get

a  

2

+b  

2

−2×8=49

a  

2

+b  

2

−16=49

a  

2

+b  

2

=49+16

a  

2

+b
