6x2-5x-21 = (3x-7)(2x+3)
The given expression can be simplified to: 8x squared +9
5x3 - 3x2 + 2x = x*(5x2 - 3x + 2) The quadratic has no real factors.
-15x2+5x=-5x(3x-1)
3x2 - 5x2 = -2x2
5x2 + 3x + 8x2 = 13x2 + 3x = x(13x + 3)

5x(3x + 1)
6x2-5x-21 = (3x-7)(2x+3)
The given expression can be simplified to: 8x squared +9
(5x 2 - 8x + 1) + (2x 2 - 4x - 11)
3x2 + 5x + 2 is a quadratic expression that can be factored as follows: 3x2 + 5x + 2 = 3x2 + 3x + 2x + 2 = 3x(x + 1) + 2(x + 1) = (3x + 2)(x + 1)
f(x) = 3x2 + 5x + 2fprime(x) = 6x + 5
6x2 + 5x - 6 is factored out to (2x + 3)(3x - 2).
5x3 - 3x2 + 2x = x*(5x2 - 3x + 2) The quadratic has no real factors.
