 03-25-2008 #1 John Mandrake Guest   Posts: n/a Please Help!!!!! =((((((((( Someone please find it in your hearts to do this! Please!!! Devide using polynomial long divison. P.S I do NOT know algebra! So I wouldn't know how to do this at all. Please take your time on this.. May it please be completed by tomorrow? Thanks (3x^2 + 11x + 1) / ( x - 3) (x^3 - 3x^3 + x - 8) / (x - 1) (10x + 27^2 + 14x + 5) / (x^2 + 2x) Devode using syntheic division (x^3 - 14x + 8) / (x + 4) (3x^2 - 10x) / (x - 6) (x^4 - 6x^3 - 40x + 33) / ( x - 7) Factor the polynomial given that f(k) = 0 f(x) = x^3 - 3x^2 - 16 - 12; k = 6 f(x) = x^3 - 11x^2 + 14x + 80; k = 8 Given one zero of the polynomial function, find the other zeros. f(x) = x^3 + 11x^2 - 150x - 1512; - 14 f(x) = 4x^3 + 9x^2 - 52x + 15; - 5 Thank you very much for taking the time to help me! Please complete by tommorow PLEASE!!! I will be your biggest fan!!! please someone help =( please I don't want to fail this grade please

Just look up how to do the polynomial division and synthetic division, I'll just give you a hint on the f(k)=0 one. Basically, if k is a root, divide out (x-k) using polynomial or synthetic (I prefer synthetic) and basically do the same for the next set too. The only reason I posted was because I recognize your username (I read the last book of the series last week). __________________ .
