Question

If x - y = 8 and xy = 5, find x2 + y2.​

Answer 1

Answer:

GIVES THAT -

$x - y = 8$

$xy = 5$

TO FIND :-

X² + Y²

SOLUTION :-

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

So ,

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

${x}^{2} + {y}^{2} = {(8)}^{2} + 2 \times 5$

${x}^{2} + {y}^{2} = 64 + 10 = 74$
