No answer in integers, nor outside the realm of imaginary numbers. Typo?
(x - 1)(2x - 9)
(2x - 1)(5x + 8)
x^3 - 121x
Factor out -2: -2(x squared +11x-20). This is fully factored.
The factors are -1(2x + 1)(3x + 4)
x = -28 / -11^2
You have to experiment with different factors of 2, and different factors of 15. In this case, 2x2 - 11x + 15 = (2x - 5) (x - 3)
(11x - 2)(3x - 5)
3x2 - 11x - 4 = (x-4)(3 x + 1)
There's a factor pair of 30 that adds up to 11. (x + 5)(x + 6)
I'm not sure this was notated correctly. As written, this is -11x plus or minus 18, which doesn't factor.
x2 - 11x + 24 = (x - 3)(x - 8)
