Question 27661
{{{ (7x^5y^5 - 21x^4y^4 + 14x^3y^3)/(7x^3y^3) }}}


Looking at the top terms, we can factorise...the 3 terms each have similar terms in them...


{{{ ((7x^3y^3)(x^2y^2 - 3xy + 2))/(7x^3y^3) }}}
{{{ (x^2y^2 - 3xy + 2) }}}


there you go. This is the answer. However, we could factorise this into (xy-2)(xy-1) too... but it doesn't ask you to do that: just a nice final thing to do to the "answer"
