Question

If (a-b)=12 and ab=14 then a²+b² =​

Answer 1

Answer:

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

(12)^2-2.14

=144-28

=116

Answer 2

Answer:

Given-(a-b) =12 and ab=14

To find-a²+b²

Solution - (a-b) =12

Squaring both sides,

(a-b) ²=12²

a²+b²-2ab=144

a²+b²-2×14=144

a²+b²-28=144

a²+b²=144+28

a²+b²=172
