What is a polynomial?

Back

A polynomial is a mathematical expression consisting of variables (also called indeterminates) raised to non-negative integer powers and coefficients. For example, 2x^2 + 3x + 1 is a polynomial.

What is a binomial?

Back

A binomial is a polynomial that contains exactly two terms. For example, x + 5 is a binomial.

What is a cubic polynomial?

Back

A cubic polynomial is a polynomial of degree three, which means the highest exponent of the variable is three. For example, x^3 + 2x^2 - 5 is a cubic polynomial.

How do you add polynomials?

Back

To add polynomials, combine like terms by adding their coefficients. For example, (2x + 3) + (4x + 5) = (2x + 4x) + (3 + 5) = 6x + 8.

What are like terms?

Back

Like terms are terms in a polynomial that have the same variable raised to the same power. For example, 3x^2 and 5x^2 are like terms.

Front

What is the degree of a polynomial?

Back

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

What is a quadratic polynomial?

Back

A quadratic polynomial is a polynomial of degree two, which means the highest exponent of the variable is two. For example, x^2 - 4 is a quadratic polynomial.

What is a monomial?

Back

A monomial is a polynomial that contains exactly one term. For example, 3x^2 is a monomial.
