Ex 25, 9Verify (i) x3 y3 = (x y) (x2 – xy y2)LHS x3 y3We know (x y)3 = x3 y3 3xy (x y)So, x3 y3 = (x y)3 – 3xy (x y) = (x y)3 – 3xySin() = 1/9 , in Quadrant II3x y = 2 replace x by 1 and the equation becomes 3(1) y = 2 do the multiplication of 3 times 1 and the equation reduces to 3 y = 2 Get rid of the 3 on the left side by subtracting 3 from both sides of the equation to reach the solution y = 2 3 = 1 So the solution to this problem is x = 1 and y = 1 Hope this helps you to
