Question

help factoring a certain type of problem? in the style of x^2 -6xn-27n^2. I can't figure it out.

Answer 1

the xs and ns are just there to throw you; focus on the numbers

Answer 2

what factors of -27 add to get -6?

Answer 3

-9 and 3

Answer 4

good then make an assumption that the problem can be solved and take a stab at setting it up:

(x-9)(x+3) ; now if we stick in an "n" we might have something that we can check

(x-9n)(x+3n) ; now check the results

Answer 5

F: x^2 O: 3xn I: -9nx L: -27n^2 = x^2 -6xn - 27n^2

Answer 6

aha! thank you.

Answer 7

youre welcome :)
