Synthetic division is a method of polynomial long division, with less writing and fewer calculations. It generally applies to division by binomials of the form x - r.
  • Impotant! Use x as the variable (i.e. not y, z, etc.) and make sure to use plus "+" and minus "-" signs, not dashes.
  • Enter a polynomial with descending powers of x.
    E.g. x3+3x2-9x+2
  • Enter the binomial divisor.
    E.g. x-5 (binomials of the form 3x-5, -x+12, etc. may also be used)
  • Click the "Divide" button.
