Haylo, to do this you need to follow a process of multiplying each
term of the first polynomial to each term of the second polynomial (in
this case, a binomial), adding or subtracting the final terms in
sequence as necessary.

Here's the solution for this problem:

(2x^3 + x^2 - 2x + 4) * (x^2 - 4)

Multiply the first part by x^2 and then the second part by -4:
    (2x^5 + x^4 - 2x^3 + 4x^2) + (-8x^3 - 4x^2 + 8x - 16)

Then, combine all of the terms with the same degree of x:
    2x^5 + x^4 - 10x^3 + 8x - 16

I hope this helps out.

To post an answer you must be a registered Google Answers Researcher. 
There is an application process involved, but as I understand it, the
application process has been closed for months due to there already
being a large number of researchers.
