what is the gcf for the following trinomial?

x^3-18x^2+28x

I am assumming you are trying to factorise

we can simply take out an x to give:

x(x^2-18x+28)

the quadratic will not factorise simply but if equated to zero would sove to give two real roots.

**David Q/R**, Saturday, September 29, 2012 at 10:44amAsking for the gcf implies that there ought to be at least two things that you're trying to factorize (because the gcf is the "greatest common factor"), whereas here there's only one. I think part of the question must have been lost somewhere.
