Consider the expressions given below. a. 2x^3-x^2-6xb. 2x^3+8x+4c. 3x^4+x^2+x-7d. 3x^4+3x^2+5x-7for each expression below, select the letter that corresponds to the equivalent expression from the given list. (4x^3-4+-x-8) is equivalent to expression (-3x^3+x^4+x)+(2x^4-7+4x) is equivalent to expression (x^2-2x)(2x+3) is equivalent to expression

The first one is B

Second there is no answer

Third is A

Do you want an explanation?

I posted how to do the first and third question. The second question is by combining like term. X^4 plus 2x^4 is 3x^4, x plus 4x is 5x and there is -3x^3 and -7. That makes the answer 3x^4-3x^3+5x-7. Sorry for the sloppy handwriting.

EDIT: I apologize for getting the second question wrong in the beginning.
