Answer: -3x^3-28x^2-x+14
Explanation:
(3x-2)(-x^2-10x-7)
1: We would usually use the FOIL method, but since we don't have binomials we are going to start with the first number in our problem.
3x x -x^2=-3x^3
3x x -10x= -30x^2
3x x -7= -21x
-2 x -x^2=2x^2
-2 x -10x= 20x
-2 x -7=14
2. Add like terms
-3x^3-28x^2-x+14
