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.

It suffices to note that the constant term must be -2.
