3x2 + 2x - 8 = 0 is a quadratic equation.
3x=2x-12x=-12
(x + 3)(3x - 2)
5x3 - 3x2 + 2x = x*(5x2 - 3x + 2) The quadratic has no real factors.
(x - 2)(2x + 7)
3x2 + 2x - 8 = 0 is a quadratic equation.
x(3x - 2)
3x2 - 2x - 5 = (3x - 5)(x + 1) = 0 gives a solution of x = 5/3 or -1. Was that what you wanted?
3x=2x-12x=-12
(x + 3)(3x - 2)
5x3 - 3x2 + 2x = x*(5x2 - 3x + 2) The quadratic has no real factors.
