Polynomial checker

This tool checks if a function f is a polynomial.

How to use this calculator?

Variable Input a single-letter that is the function variable. Examples :
function = 4x+1 , then input variable = 'x'
function = 9t + 5 , then input variable ='t'
function Are accepted :
  • The function variable
  • Integer numbers (-4) or fractions (1/4) or decimals (3.6).
  • Operators : + - * / ^ (the last is the power operator so x^2 = `x^2`)
  • Parentheses : used for expressions like (x^2+1)(x-5)
Examples Function = x^2-4x+1 (variable = 'x')
Function = (x^2-1)(x-5)-3 (variable = 'x')
Function = x^3-4/3*x^2+1 (variable = 'x')
Function = 0.23*t^2-1/5*t+1/2 (variable = 't')
