Question

If x = 2 and y = -3, find the value of (x-2y)/(x+2y)

Answer 1

Answer:x2−y2=12xy

Dividing with xy ,

xy−yx=12

Taking squares on both the sides ,

(xy−yx)2=122

⇒x2y2+y2x2−2=144

⇒x2y2+y2x2=146

Step-by-step explanation:

Answer 2

Answer:

Given,

n=2, y=-3

therefore, by putting the given values in the equation,__

= 2-2(-3)/2+2(-3)

=2+6/2-6

=8/(-4)

=-8/4

= -2

Ans: -2
