Question

If a-b=3and a square+ b square= 29 find the value of ab is

Answer 1

a-b=3
a square +b square =29
a=5 square
b=2 square
ab=5×2
=10

Answer 2

Given (a - b) = 3.

On Squaring both sides, we get

(a - b)^2 = (3)^2 

a^2 + b^2 - 2ab = 9

29 - 2ab = 9

2ab = 20

ab = 20/2

ab = 10.


Hope this helps!
