2x2-x-15 = (2x+5)(x-3) when factored
2x(x^2+x-6)
(2x - 3)(x + 2)
(x - 2)(2x + 3)
2x2 + 6xy = 2x (x + 3y)
2x squared - 5x - 3 = (2x +1)(x -3)
(x - 5)(x + 3)
x2 - 2x = x(x-2)
No.
x(x + 2)

You have to experiment with different factors of 2, and different factors of 15. In this case, 2x2 - 11x + 15 = (2x - 5) (x - 3)
x(x - 2)
(x + 5)(x - 3)
