Question

X + Y = 74 ,XY =12 then find X square + Y square​

Answer 1

Hey there!

Given,

xy = 12

(x + y) = 74

Squaring both sides,

( x + y)² = (74)²

x² + y² + 2xy = 5476

x² + y² + 2*(12) = 5476

x² + y² + 24 = 5476

x² + y² = 5476 - 24

x² + y² = 5452

Answer 2

Answer:

Step-by-step explanation:

x + y = 74

xy = 12

squaring both sides

(x + y)² = 74²

x²+y²+2xy = 5476

x²+y²+2(12)+ 5476

x²+y²=5476-24

x²+y²=5452
