x + 3
what is -12X squared +28X - 15? i figured it out myself. its (-6X + 5)(2X - 3).
It is impossible but if it were x squared plus 2x minus 15 the equation would be (x+5) (x-3) with x being equal to either -5 or 3. If the original problem was x squared minus 2x minus 15 the equation would be (x-5)(x+3) and x would be equal to either 5 or -3
x2 + 2x - 15 = 0(x + 5) (x - 3) = 0x = -5x = +3
2s2+7s-15 = (2s-3)(s+5) when factored
3x2-39x-90 = (3x+6)(x-15) when factored
2x2 + 7x - 15 = (2x - 3)(x + 5)
That can be factored to -((x + 5)(x - 3))

2x2-1x-120 = (2x+15)(x-8) when factored
It is a quadratic expression which when factored is (2y+3)(y+5)
8x2-39x+45 = (8x-15)(x-3) when factored
-15
Divide all terms by -1 and rearrange in the form of a quadratic expression: So: x2-x-3390 = (x-58.72585336)(x+57.72585336) when factored
-13
(2x+1)(2x+3) when factored
