According to Wikipedia, in mathematics, a polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.

Calculate Polynomials with Nickzom Calculator
For Nickzom Calculator, there are two polynomials which are cubic and quartic.
A cubic equation or polynomial has a degree or order of 3 whereas a quartic equation or polynomial has a degree or order of 4.
Let’s start with a cubic equation
Find the roots of f(x) = 2x3 + 3x2 – 11x – 6 = 0, given that it has at least one integer root.
From the example above, you can see that the coefficient of x3 is 2, the coefficient of x2 is 3, the coefficient of x is -11, the constant before the equality sign is -6, the constant after the equality sign is 0.

From Nickzom Calculator – The Calculator Encyclopedia, the values of x are: 2, -0.5 and -3.
Now, let me show you how to use Nickzom Calculator – The Calculator Encyclopedia to get answers for a quartic equation.
Find the roots of f(x) = 3x4Â Â + 6x3Â Â – 123x2Â Â – 126x + 1080 = 0, given that it has 4 real roots.
From the example above, you can see that the coefficient of x4 is 3, the coefficient of x3 is 6, the coefficient of x2 is -123, the coefficient of x is -126, the constant before the equality sign is 1080 and the constant after the equality sign is 0.
