Answer

$(x+18)(x-20)$

Work Step by Step

$x^2-2x-360$ has no common monomial factors. =$(\ \ \ \ \ \ \ \ \ )(\ \ \ \ \ \ \ \ \ )$ =$(x\ \ \ \ \ \ \ )(x\ \ \ \ \ \ \ )$ =$(x+\ \ )(x-\ \ )$ The factors of -360 must have unlike signs. =$(x+18)(x-20)$ 18 and -20 have a sum of -2 and a product of -360.
