    Forget about what's written. You know how to dance terms ?

    Powers in the denominator and numerator cancels each other. If we have common factors, the powers in the numerator - powers in the denominator gives you simplified form

    The problem now is to find these common factors, well you can't tell that you have or don't have common factors unless you factor all the expression to the prime factors, like x^2-1 =(x-1)(x+1)

    Um what? O.o I just want to know how the example got x^6 and x^8 is x^6 and same for y

    I told what's written is confusing, it's trying to say that x^8=x^6*x^2, so x^8/x^6= x^2

    Basically, we express this procedure by saying power of the numerator-power of the denominator

    The answer is not in the simplified form. He was writing the similar terms in top of each other, so that he can cancel them easily

    Um okay.. Then y is 1?

    The expression will develop to simple form, 95% percent you will NOT get a number, just x and y

    In our case, it's ((x-6)*y)/x^2

    Okay.. For the problem im working on-- x^4-x^5=? y^6-y^5=? x=-1 y=1

    The original problem is --- Multiply- x^3-64/ x^5y^5 * x^4y^6/x^2+4x+16

    The final form is (x-4)*y/x, I followed exactly the same procedure, now just the numbers..

    Don't ignore anything \[((-1)-4)*1/(-1)=?\]
