( x - y) = 5
take square both side
x^2 + y^2 -2xy =25
x^2 + y^2 =25 +2xy
=25 + 2(6) = 25 + 12
=37

You cannt square both sides you have to use formula

Hi!
You have to use the formula [tex](x-y) ^{2} = x^{2} + y^{2} -2xy
So basically you have to square the (x-y) and solve.
Therefore the answer is 37.
Hope this helps you!

So now you have to substitute the values given
x-y is given as 5
now you take it easily by put value
Wait I will send pic
yes
yess correct
sorry abhi your answer is correct
but you have to use formula
dear use general way which understand another person easily
ou won't get marks then
