Factor Completely

Factor the polynomial completely.  If the polynomial cannot be factored, say it is prime.

Problem 90; page 58.

x^3 + 8x^2 - 20x

GCF = x

x(x^2 + 8x - 20)

x(x - 2)(x + 10)

Nothing else can be done here.

You say?

3 linear factors! I'd say that is fully done.

The x^3 term tells me that there are 3 linear factors that must be found.
