THUMBNAIL BY: @TNTsquirrel Synthetic division is used to divide polynomials which are being divided by a linear factor. Example: f(x)= 2x^3-15x^2+34x-21 ; x-1 "x-1" is the linear factor, the rest is the polynomial Example answers to enter into the calculator: Enter a 3, then 2, then -15, then 34, then -21, then -1. (made this to do my homework, maybe you can find it useful too)
