What is the degree of a polynomial function?

Back

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

How do you find the zeros of a polynomial function?

Back

To find the zeros of a polynomial function, set the function equal to zero and solve for the variable.

Front

What is a factor of a polynomial function?

Back

A factor of a polynomial function is a polynomial that divides the function without leaving a remainder.

How do you perform polynomial long division?

Back

Polynomial long division involves dividing the leading term of the dividend by the leading term of the divisor, multiplying the entire divisor by that result, and subtracting from the dividend.

What are the steps to factor a cubic polynomial?

Back

1. Look for common factors. 2. Use synthetic division or polynomial long division if necessary. 3. Factor the resulting quadratic if possible.

Front
