factor x^2-6x-2016

Factor the following:
x^2 - 6 x - 2016

The factors of -2016 that sum to -6 are 42 and -48. So, x^2 - 6 x - 2016 = (x + 42) (x - 48):
Answer: |(x + 42) (x - 48)

x^2 - 6x - 2016

Factor 2016  =

504 * 4

252 * 8

126 * 16

42 * 3 * 4 * 4

21 * 2 * 3 * 4 * 4

[7 * 3 * 2] * [3 * 4 * 4]

42  * 48

And we need

42 and - 48  = - 6

(x + 42) ( x - 48)
