3x(2x + 1)
your equation is this... 2x3 + 11x = 6x 2x3 + 5x = 0 x(2x2 + 5) = 0 x = 0 and (5/2)i and -(5/2)i
(2x-4)(x-1) = 0
(x-3)(x-5) = 0
(x-3)(x-9) = 0
(x+4)(x-5) = 0
(x - 6)(x - 2)
63
It can be simplified in the form of: 2x3+9x2-7x-34 = 0
If you mean: x2+9x+20 then it is (x+4)(x+5) = 0 when factored
(x + 3)(x + 2)
2(x - 2)(x - 4)
