Weegy: You need to factor 2x^2 +3x -9... you probably learned FOIL (First, Outside, Inside, Last)... [ you use that to find the two terms you can multiply...
2x^2 + 3x -9 = (2x-3)(x+3) = 0
So you need to find when one of the two terms = 0, because when you multiply anything by 0 you get 0...
(2x-3) = 0 when x = 1.5
(x+3) = 0 when x = -3
So x = 1.5 or x = -3 ] selymi|Points 8442|
