Question

If a-b=8 and a+b=6 then a²+b²is ??

Answer 1

Answer:

a²+b² = 50

Step-by-step explanation:

a-b=8

a=8+b              ----------------1

a+b=6             ----------------2

Subs value of a from 1 in 2,

8+b+b=6

2b=-2

b= -1                   ----------------3

Subs value of b from 3 in 1,

a=8+(-1)

a=7

So,

a²+b² = (7)²+(-1)² = 49+1 = 50
