Long divide the coefficients to find:
#(-7x^3-5x^2-2x-4)/(x-4) = -7x^2-33x-134 - 540/(x-4)#
The quotient is
Explanation:
I like to long divide the coefficients like this:
The process is similar to long division of numbers.
In this particular example we find:
#(-7x^3-5x^2-2x-4)/(x-4) = -7x^2-33x-134 - 540/(x-4)#
That is
Or if you prefer:
#-7x^3-5x^2-2x-4 = (-7x^2-33x-134)(x-4)-540#
