SOLUTION: We learned how to factor trinomials awhile ago, by unfoiling like {{{x^2+2x-3}}} would be (x+3)(x-1), but how do you do it if there is a coefficient in front of the {{{x^2}}} like

Question 300802: We learned how to factor trinomials awhile ago, by unfoiling like would be (x+3)(x-1), but how do you do it if there is a coefficient in front of the like i used to just factor it out when they were simple bye just making like into but it dosent work like that anymore because im getting ugly decimals. Please help.
Answer by Stitch(470) (Show Source): You can put this solution on YOUR website!
Given:
You still use the unfoil method however you need to include the coefficient.
Find the factors of 22: 1,2,11,22
You need to look at those factors and figure out how to get -17 while using the coefficient with one of the factors.
-17 = -11 - 3*(2)

Set that equal to 0 to solve for B
