How do you factor x23x2 I need to find the roots of the equa
How do you factor (-x^2-3x-2) I need to find the roots of the equation using this trinomial. I know there are 2 imaginary roots but dont know how to show work for it. If someone could please help Id really appreicate it. Thanks.

Solution
(-x^2-3x-2)
find the roots : -x^2 -3x -2 =0
factorise the equation : -x^2-2x -x -2 =0
-x( x+2) -1(x +2) =0
(-x -1) (x +2) =0
x = -1 ; x =-2
So, (-x^2-3x-2) = (x+2)(-x -1)
