Guide through it will be appreciated, thanksSimplify:
(x^2 - y^2 - 2x - 2y) X (xy-3y^2)
(x^2 - 2xy - 3y^2) X (y-x+2)
Take out a factor of y on the top from the last bracket, and factorise the first bracket on the bottom:
Cancel the term which appears on both the top and bottom:
Expand the brackets on the bottom:
Take out a factor of on the bottom:
Now cancel the term which appears on the top and bottom of the fraction:
