2. simplify the following expression.
4(9+ 3x) + (2x2 - 1) – 15 – (2x + 6) + x2

A. is the answer in this question

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
