If that were x^2 - 3x - 4, it would be (x + 1)(x - 4)
As it is, it doesn't factor neatly. Applying the quadratic formula, we find two real solutions. (3 plus or minus the square root of 41) divided by two.
x = 2.350781059358212
x = -0.8507810593582121

You have : 2x^2 - 3x -4 . This equation can't be factored using normal means of factoring. The 2 with the x^2 is the big problem for getting the equation into a normal factored form.
2x squared minus 5x minus 3 factored is (2x+1)(x-3).
6x2 + 5x - 6 is factored out to (2x + 3)(3x - 2).
2x squared - 5x - 3 = (2x +1)(x -3)
(x - 2)(2x + 3)
