User: Solve for x. 4 - 3x = 2x + 9

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 ]
