What is the answer to 24x3-5x2-48x-8 divided by 8x plus 4?
If you notice, 8x + 4 = 4(2x + 1), but there is an odd
coefficient for x2, so there is guaranteed to be some remainder
(that is 8x + 4 is not a factor of the polynomial):
(24x3 - 5x2 - 48x - 8) ÷ (8x + 4) = 3x2 - 2x - 5 - (x2 - 12)/(8x
+ 4)
