Something wrong with that equation: CHECK IT! It's probably + 90, not - 90
And show your work: NO homework done here...
Something wrong with that equation: CHECK IT! It's probably + 90, not - 90 \(\displaystyle \ \ \ \) Changing it from "+ 90" to " - 90+" doesn't make the result even near 0.

NOPE, its -90. The problem is correct .
(x^3 - 8x^2 - 3x + 90) / (x - 5) = x^2 - 3x - 18
Should have mentionned that problem should PROBABLY be:
x^3 - 8x^2 - 3x + 90 = 0; +5 (instead of X^3-8x^2-3x-90=0; -5)
