Question

In your own words, explain how a trinomial of the form 2x2 + 13x + 15 can be turned into a four term polynomial suitable for factoring by grouping. Use complete sentences.

Answer 1

You would need something like kx^2 + ax + bx + c, assuming a and b are constants
In this case, sum would have to be 13 and product to be 2*15=30
