Use the table below to find the products of the two polynomials. Enter your answer in descending order in the box below. Enter exponents using the caret ( ^ ). For example, you would enter as 4x^2. Do not enter spaces in your answer.
(x3 + 2x2  2)(x3  3x + 3)how do you do this?

Just multiply term by term, just as you do with a multidigit number:
124* 327 = 100(300+20+7) + 20(300+20+7) + 4(300+20+7)
(x^3 + 2x^2  2)(x^3  3x + 3)
= x^3(x^3  3x + 3) + 2x^2(x^3  3x + 3)  2(x^3  3x + 3)
= x^6  3x^4 + 3x^3 + 2x^5  6x^3 + 6x^2  2x^3 + 6x  6
= x^6 + 2x^5  3x^4  5x^3 + 6x^2 + 12x  6 
Ahem. Make that + 6x

thanks :)
