x2 + 5x +
not really sure what that extra plus is for...
this is the most you can factor it...
x(x + 5)
(x + (1 - 2i))(x + (1 + 2i)) where i is the imaginary square root of -1
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
5(x + 3)(x + 1)
(x + 5)(x + 8)
x(x + 2)(x + 3) x = 0, -2, -3
(5x + 6)(x + 4)
x(x2+5x+6)
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
5(x2 + x + 1)
(x+1)(x+4)
(x + 3)(x + 2)
(x - 1)(5x + 7)
(5x - 2)(x - 5)
(x + 3)(x + 2)
(x-1)(x-4)
There are no rational factors.
5(x^2 + 9)
(2x + 1)(x + 2)
