What is a polynomial?

Back

A polynomial is a mathematical expression consisting of variables (or indeterminates) raised to non-negative integer powers and coefficients. For example, f(x) = 2x^3 - 3x^2 + 4x - 10 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 polynomial. For example, in f(x) = 2x^3 - 3x^2 + 4x - 10, the degree is 3.

What are the zeros of a polynomial?

Back

The zeros of a polynomial are the values of x that make the polynomial equal to zero. They are also known as roots.

How do you find the zeros of a polynomial?

Back

To find the zeros of a polynomial, set the polynomial equal to zero and solve for x. This may involve factoring, using the quadratic formula, or other methods.

Front

What is multiplicity in relation to polynomial zeros?

Back

Multiplicity refers to the number of times a particular zero is repeated in a polynomial. For example, if (x - 2) is squared in the polynomial, then 2 is a zero with multiplicity 2.

What is the significance of the leading coefficient in a polynomial?

Back

The leading coefficient is the coefficient of the term with the highest degree. It affects the end behavior of the polynomial's graph.

Front

What does the graph of a polynomial function look like?

Back

The graph of a polynomial function is a smooth, continuous curve that can have various shapes depending on the degree and leading coefficient.

Front

What is the relationship between the degree of a polynomial and the number of zeros?

Back

A polynomial of degree n can have up to n real zeros, counting multiplicities.

Front

How do you determine the end behavior of a polynomial function?

Back

The end behavior of a polynomial function is determined by the leading term. If the leading coefficient is positive, the ends of the graph will rise; if negative, the ends will fall.

Front

What is synthetic division?

Back

Synthetic division is a simplified method of dividing a polynomial by a linear factor, which is faster than long division.
