If `a+b=11 and a-b=7`, then ab=

If a + b = 11 and ab = 15, then a ^(2) + b ^(2) is equal to :

If a+ b =1 and a-b =7, find : ab

If a + b = 11 and ab = 15, then a^2+b^2 is equal to : यदि a+b = 11 और ab = 15 है, तो a^2+b^2 का मान किसके बराबर है ?

If a+b=7 and ab=10, then find a−b.

If a+b=7 and ab=12, find the value of (a^(2)-ab+b^(2))

If a+b=7 and ab=12, find the value of (a^(2)-ab+b^(2))

If (a - b) = 7 and ab = 9, then (a^(2) + b^(2)) = ?
