What is a solution to a function?

Back

A solution to a function is a value of the variable that makes the function true. For example, if f(x) = 0, then x is a solution if substituting x into the function results in 0.

What is the degree of a polynomial?

Back

The degree of a polynomial is the highest power of the variable in the expression.

Front

What is the difference between a monomial and a polynomial?

Back

A monomial is a single term, while a polynomial is a sum of two or more monomials.

Front

What is the process of factoring a polynomial?

Back

Factoring a polynomial involves rewriting it as a product of its factors, which can be simpler expressions.
