 `multiply (2x^3+x^2-2x+4)* (x^2-4)` Subject: Re: algebra Answered By: joey-ga on 06 Jan 2005 22:06 PST
 ```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. --Joey``` ```How come you can post your answer on the website!
