sorry but on the last question i posted the wrong equation...

(3x^2-8x+1)(-2x^2+x-2)

I have heard of the FOIL process but i still tend to do the problems wrong...

    You distribute.
    What you do is, multiple the first number from the first bracket with the first number from the second bracket, then the second number from the second bracket and the third number from the second bracket. You then multiple the second number from the first bracket with the first number from the second bracket, then the second number from the second bracket and the third number from the second bracket. You do the same for the third number in the first bracket.

    After you distribute, you should get:

    (-6x^4 + 3x^3 - 6x^2 + 16x^3 - 8x^2 + 16x - 2x^2 + x - 2)

    Then, you find common factors and add or subtract them, for example:

    x^2 + 3x^2 + 4x + 6
    = 4x^2 + 4x + 6

    Remember when you multiple with exponents, you must add them and if you divide with exponents, you divide them.

    Need to make correction on what I wrote previously...

    Remember when you multiple with exponents, you must add them and if you divide with exponents, you *subtract* them.
