Factoring a trinomial-In Algebra a trinomial is a polynomial with three terms. Use this method I call the "rainbow method" to help with your factoring.
This rainbow method works great with a trinomial with a led coefficient greater than one, and there is not a greatest common factor.
Example problem 1 Factor 6x^2 +7x -5
Example problem 2 Factor 15x^2 + 17x -4
