factorize x^-6x-27

I expect you mean \(x^2-6x-27\)

You have to look for 2 numbers that multiply to -27 and add to -6

Since they mult to a minus number, one must be positive and one must be negative.

Since they add to a minus number the bigger one is the negative one.

-9 and 3 are the numbers

\(x^2-6x-27=(x-9)(x+3)\)
