Homework Help: 9th grade Algebra

Posted by Reed on Wednesday, August 22, 2012 at 9:25pm.

Did I get the right answer for this? Evaluate the expression
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?
