SUPER BASIC PRE ALGEBRA QUESTION?

I'm in ALG2 and I forgot about a basic Pre Alg thing.

Review sheet says:

3x^2 - 2x; Evaluate if x=-2

Now I'm not sure if the exponent is for the product of 3 and -2 or just the -2 (x)

Thanks

    How did you do on the mathematics area of the SATs? That demands Algebra. I recommend paying for a homeschool curriculum for Algebra to do at abode. you will get a stable, complete 2 semester Algebra course for around 60 funds. that's the comparable concern taught in inner maximum faculties and is particularly like what instructors coach, you in basic terms coach your self with the help of reading and doing artwork. the main suitable concern is you're able to do it at your individual %., and you may end it in some weeks, or it may take you till the top of this college year. you will nonetheless study each and every thing you opt for for.
