Question

find the value of x2+y2​

Answer 1

Answer:

80

Step-by-step explanation:

we know that (x+y)^2= x^2+y^2+2xy

(x+y)^2-2xy= x^2+y^2

(12)^2-2*32=x^2+y^2

x^2+y^2= 144-64

x^2+y^2= 80

Answer 2

Answer:

80

Step-by-step explanation:

x+y=12. , xy=32

x2+y2

=(x+y)2-2xy

=(12)2-2×32

144-64=80
