The question that Mr. Kirk helped me with a little while ago. I am trying to do it on my calculator this time. I cannot seem to come out with the answer. I can't seem to get a logical answer. Will you please explain it to me? I just cannot grasp it!!
Here'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
