Question

Hiii guys!!✌✌

If x + y = 12 and xy = 14, find the value of (x^2 + y^2).

Plz solve it ⬆️⬆️

​

Answer 1

Answer:

Given - X+ y= 12

Xy = 14

to find - X^2 + y^2

solution -

X+y= 12

(X+y)^2 = 12^2

X^2 +y^2 +2xy= 144

X^2 + y^2 + 2(14) = 144

X^2 + y^2 +28= 144

X^2 + y^2 = 144-28

X^2 + y^2= 116

Answer 2

Answer:

130

Step-by-step explanation:

${x}^{2} + {y}^{2} = {(x + y)}^{2} - xy$

We already have the values so substitute them..

${x}^{2} + {y}^{2} = {(12)}^{2} - 14 = 144 - 14 = 130$

Hence ur answer is 130...
