Polynomial Equations Formula Example of a polynomial equation is: 2x2 + 3x + 1 = 0, where 2x2 + 3x + 1 is basically a polynomial expression which has been set equal to zero, to form a polynomial ...

Polynomial: A mathematical expression consisting of variables and coefficients, involving operations of addition, subtraction, multiplication, and non-negative integer exponents.

Polynomial equations are mainstays of high-school algebra — expressions like x^2+5X+6 = 1 — in which variables are raised to the whole number exponents and added, subtracted and multiplied.
