What is a polynomial?

Back

A polynomial is a mathematical expression consisting of variables (also called indeterminates) raised to non-negative integer powers, along with coefficients. For example, 4x^3 - 2x + 5 is a polynomial.

What is the degree of a polynomial?

Back

The degree of a polynomial is the highest power of the variable in the expression. For example, in 3x^4 + 2x^2 - 5, the degree is 4.

What does it mean to factor a polynomial?

Back

Factoring a polynomial means expressing it as a product of its factors, which can be polynomials of lower degrees.
