    Synthetic divison

    i am stuck on this problem for my pre calc class. any help would be greatly appreciated.

    Suppose you want to divide 3x^4-2x^3+x^2-2x+5 by 2x+3. How might you change this problem so that synthetic division can be used to get the correct answer?

    i know that synthetic division can only be used if it is (x-c) because the coefficient of x may only be positive one. but thats it.

    Thank you very much.

    Solve for 2x + 3 = 0 and then use synthetic division. If you don't know what that is here is a good link for it. (It is at the bottom of the page)

    Yes. Read the bottom of the link I gave you in the earlier post to know how to set it up.
