I put the . there to show its times because I don't know how to put the dot in between the problems

lot of factoring and canceling for this one
you need the steps?

actually factors as this
\[\frac{2(x-y)6(x+y)}{3(x+y)(x+y)(x-y)}\]

so you factor as much as you can to see what factors you might have in common in the numerator and denominator. then you cancel each factor you have in common to reduce the fraction

when you get this
\[\frac{2(x-y)6(x+y)}{3(x+y)(x+y)(x-y)}\] then you get rid of all common factors

so finally you get
