use long division to divide these two polynomials and show all of your work.

(2x^4 - 3x^3 - 57x^2 - 128x - 84) ÷ (2x + 3)

is this a factor of the original polynomial?

you in advance i really need the asap!

I think this will might help you out with my notes(:

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
