Question

If x 2 + y 2 = 7xy, show that x 2/ y2 + y 2 /x 2 = 47​

Answer 1

Step-by-step explanation:

x2+y2=7xy

dividing the equation by xy

x/y+y/x=7

squaring both sides....

(x/y+y/x)^2=49

x2/y2+y2/x2+2=49

x2/y2+y2/x2=47

hence proved

Answer 2

You are lucky that you got it, next week you won't and I will assure you that.

Just joking
