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