Question

How would you simplify?
x^3+5x^2-16x-80/x^3+4x^2-24x-100

Answer 1

Notice, in the numerator, how the third and fourth coefficients are 4 times the first and second coefficients? And in the denominator, they are 5 times? So where you want to start is by grouping the first and second coefficients and the third and fourth coefficients and see where it gets you.
