# Math Help - Synthetic divison

1. ## 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.

2. 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)

so i should divide $3x^4-2x^3+x^2-2x+5$ by $-3/2$?

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

Latex hint: For fractions try using \frac{a}{b} it will come out like this $\frac{a}{b}$

thanks, i read the page. also i was trying to figure out the codes for this site but never fully did. is there a web page or something explaining all of the codes?

6. Yes there is a very good tutorial for LaTeX here: About LaTeX
