For this question, we need to use the Distributive Property:
2(x^2 – 1) = 2x^2 – 2
3x(x – 4) = 3x^2 – 12x
Michael Paul Goldenberg’s excellent comment was that the constant term must be -2 and that leads us right to the answer! Thanks
Combine like terms and only the x^2 are combinable.
A way to check your work is to put 2(x^2 – 1) + 3x(x – 4) into Y1 and to put each multiple choice answer into Y2 and then compare to see if the tables for Y1 and Y2 are equivalent.
