x^2 - 8x + 64 remainder 217 or you could write it as
(x^2 - 8x + 64)+ 217/(x + 8)
Step-by-step explanation:
You first need to write the polynomial in descending order of degree with zero coefficients for x^2 and x terms, so here we have:
x^3 + 729 = x^3 + 0x^2 + 0x + 729
So dividing by x+8:-
x^2 - 8x + 64 <the quotient.
x + 8 ) x^3 + 0x^2 + 0x + 729
x^3 + 8x^2
- 8x^2 + 0x
-8x^2 - 64x
64x + 729
64x + 512
217 = Remainder.
