2) Find the values of a and b so that the polynomial x ³-ax²-13x+b has (x-1) and (x+3) as a factor.
To find the values of the constants in the polynomial, you should try to group them first. Therefore, x^3 + ax - 13x + b = x (x + a) ? 1(13x + b). Then, find the GFC for each set and factor out the given terms. Go to http://www.dummies.com/how-to/content/how-to-factor-a-polynomial-expression.html for more help.
