Question

Solve for "K" in the following polynomials given the binomial that is a factor of the polynomial (using synthetic division)


x^3 + kx^2 - 72 (x+3)

Answer 1

Same process as previously, except we have to include a '0' in place of the linear term.

-3 | 1 k 0 -72

--------------------------------------------------
(remainder)
Then we just set the expression we find for remainder equal to zero and solve for k.

Think you can do this one now? :)
