Answer:
B. 2
Step-by-step explanation:
Assuming the term is meant to look like this: -3x², then the answer is B.2. An exponent is a superscript (super means above, script means writing) that tells you to multiply something by itself.
In this case, -3x² means -3·x·x
If it was written as (-3x)², it would mean (-3x)·(-3x)
It would be 50+ 5x=10. Hope that helped!
