Best ResponseYou've already chosen the best response.0I see that this is second same question :) I'll help you make it clear, so you can easily do any of them by yourself :) You can ALWAYS use formula! http://en.wikipedia.org/wiki/Quadratic_equation For x1 you will get 3/4, and for x2 you will get 2/5 So you have: 1) x=3/4 ALL you do is > x3/4=0 2) x=2/5 ALL you do is > x+2/5=0 So result you want is (x3/4)*(x+2/5) Clear enough? :) Hope I helped! Good luck

Best ResponseYou've already chosen the best response.0I started with 2 products of the first term (5 and 4). Then I chose 2 products of the last term (2 and 3) I set it up like this (5x 3)(4x 2) I knew i needed the sum to be 7 so the only way that would work is 158. So I flipped it to (5x 2)(4x 3) then I filled in the signs

Best ResponseYou've already chosen the best response.0I like the quadratic formula tho. Their answer matched mine if you just get rid of the fractions. I'd stick to that. easy
