**Ms. Sue**, Wednesday, August 22, 2012 at 9:51pmHere's your original problem.

3x squared - 5x when x= -2 My Answer is 46. I got this by doing 3 times -2 and squaring that and then multiplying 5 times -2 and subtracting that ( negative 10 ) from 36. Is this correct?

3x squared - 5x

(3 * -2)^2 - 5(-2)

-6^2 + 10

36 + 10 = 46
