What is a binomial?

Back

A binomial is a polynomial that contains exactly two terms, such as (3x + 4) or (5y - 2).

How do you add binomials?

Back

To add binomials, combine like terms by adding the coefficients of the same variable. For example, (2x + 3) + (4x + 5) = (2x + 4x) + (3 + 5) = 6x + 8.

What are like terms?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and 5x are like terms, but 3x and 4y are not.

How do you subtract binomials?

Back

To subtract binomials, distribute the negative sign and then combine like terms. For example, (5x + 3) - (2x + 1) = (5x - 2x) + (3 - 1) = 3x + 2.

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 4x^3 + 2x^2, the degree is 3.

What is a polynomial?

Back

A polynomial is an expression that consists of variables raised to non-negative integer powers and their coefficients, such as 2x^2 + 3x + 1.
