    Synthetic division 2

    sorry, this is a hard work sheet. I have another little synthetic division.

    you have to divide 3x^5-3x^4+3x^2-3x+10 by x+2. when i did this i got (3x^5+3x^4+6x^3+16x^2+29x)+ \frac {68}{3x^5-3x^4+3x^2-3x+10}

    so when i do ((3x^5+3x^4+6x^3+16x^2+29x)+ \frac {68}{3x^5-3x^4+3x^2-3x+10} times (x+2) the graph is different from 3x^5-3x^4+3x^2-3x+10, but only by a little bit. can anyone see where i messed up?

    Thank you so much and i appreciate all the help!

    Hi,

    I don't know what you have actually done but your result is not correct.

    (3x^5-3x^4+3x^2-3x+10) \div (x+2) = 3x^4-9x^3+18x^2-33x+63- \frac{116}{x+2}
