Question 300802: We learned how to factor trinomials awhile ago, by unfoiling like x%5E2%2B2x-3 would be (x+3)(x-1), but how do you do it if there is a coefficient in front of the x%5E2 like 3b%5E2-17b%2B22 i used to just factor it out when they were simple bye just making like 2x%5E2%2B4x%2B6 into 2%28x%5E2%2B2x%2B3%29 but it dosent work like that anymore because im getting ugly decimals. Please help.
