This does readily factor!!!
So by trial and error.
Discount '0' because the you are left with '-7'
Try '-1
(-1)^(3) - 5(-1)^(2) - 13(-1) - 7 =>
-1 - 5 + 13 - 7 adding = '0'
Hence x = -1
Therefore ( x + 1) is a factor.
(x+1)
( x^(3) - 5(x^(2) - 13x - 7 = (x^(2)
-x^(3) -x^(2) =
-6x^(2) - 13x = ( x^(2) -6x
6x^(2) + 6x =
-7(x + 1) ( x^(2) - 6x + 7)
(x + 1)(x^(2) - 6x + 7) is fully factored.
If you factor the Quadratic, you will move into the region of IMGINARY (i) numbers.

What are the factors of 5x2-13x?
5x^2 - 13x = x(5x - 13)
Find the factors of x3-5x2 8x-4 how to solve this equation?
5x2-8x-4
How do you factor x3 plus 5x2 minus 16x minus 80?
To factorise x3 + 5x2 - 16x - 80 I note that -80 = 5 x -16 and 5 & -16 are the coefficients of x2 and x. Thus I have: x3 + 5x2 - 16x - 80 = (x + 5)(x2 - 16) and the second term is a difference of 2 squares, meaning I have: x3 + 5x2 - 16x - 80 = (x + 5)(x + 4)(x - 4)
X3 - 14x2 plus 13x?
