2x2-1x-120 = (2x+15)(x-8) when factored
If you mean (1+2x)2, that is already factored.
2x2+5x+3 = (2x+3)(x+1) when factored
x2 - 2x = x(x - 2)
(2x+10)(x+4)
2x2-1x-120 = (2x+15)(x-8) when factored
If you mean (1+2x)2, that is already factored.
2x2+5x+3 = (2x+3)(x+1) when factored
x2 - 2x = x(x - 2)
(2x+10)(x+4)
2x squared minus 5x minus 3 factored is (2x+1)(x-3).
2x2 + 5x = x*(2x + 5)
(4+x) (2x-3)
(2x - 1)(x + 3)
2x2 + 7x - 15 = (2x - 3)(x + 5)
It is (2x-5)(x-4) when factored
3x2-2x-8 = (3x+4)(x-2) when factored
