Question

If AB equal to 8 and a + b equal to 6 then the value of (a square + b square)

Answer 1

Step-by-step explanation:

a×b=8

a+b=6

so, a=4 and b=2 or vice versa

so, a2 +b2= 4×4+2×2

16+4=20

ANS=20

Answer 2

ab=8

a+b=6

Step-by-step explanation:

a^2+b^2=(a+b)^2-2ab

=(6)^2-2×8

=36-16

=20
