Question

help my daughter has a math problem and came to me for help, I am lost....
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.

Answer 1

Asking 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.
