    To multiply this, we will use the FOIL method :) Multiply the first numbers of each parenthesis, the outside numbers of each parenthesis, the inner numbers of both parenthesis, and the last numbers of the each parenthesis. |dw:1348014504002:dw|

    So we got our first part, 5x*3x. We multiply the coefficients, which gives us 15, and then we add the exponents x^1+x^1=x^2. That means our first part is 15x^2. Now for the 2nd part we have, 5x*-1, and all we do here is multiply the numbers as well, so we get -5x. Now we got the 3rd part, 2*3x. All we do here is multiply the numbers and that then gives us 6x. Finally we have the last part 2*-1, which is just -2. So now we have 15x^2-5x+6x-2, which when you combine -5x & 6x, gives you 15x^2+x-2 :)

    Even though FOIL is what everyone else uses, I like solving them like this : |dw:1348015657898:dw| On the top is the first parenthesis set, the left the 2nd just multiply in the middle :) Tell me if you get it.

    And then we have x^3-x^2-2x^2+2x+x-1. We can combine -x^2-2x^2 & that gives us -3x^2. Also, 2x+x=3x. So now we have x^3-3x^2+3x-1 as our answer :)
