Simplify.

x^2 + 5x - 14

__________

x^2 + 8x + 7

A) 7x/x

[x ^3 - 2x^2 + 3  ] / [ x -2 ]

Because the polynomial in the  numerator is of a greater degree than the polynomial in the denominator, there is no horizontal asymptote

x^2 + 5x - 14                                  [ ( x + 7) (x - 2) ]                         [ x - 2 ]

__________        factors as           _____________      =                ______

x^2 + 8x + 7                                   [ (x + 7) ( x + 1) ]                        [ x + 1 ]
