Remainder and Factor Theorem - Flashcard 2

Front

What is the Remainder Theorem?

Back

The Remainder Theorem states that if a polynomial f(x) is divided by (x - c), the remainder of this division is equal to f(c).

What is the Factor Theorem?

Back

The Factor Theorem states that (x - c) is a factor of the polynomial f(x) if and only if f(c) = 0.

How do you determine if a binomial is a factor of a polynomial?

Back

To determine if a binomial (x - c) is a factor of a polynomial f(x), evaluate f(c). If f(c) = 0, then (x - c) is a factor.

How do you find the remainder when dividing a polynomial by a binomial?

Back

You can find the remainder by evaluating the polynomial at the value that makes the binomial zero, using the Remainder Theorem.

What is the significance of the coefficients in a polynomial?

Back

The coefficients of a polynomial determine the shape and position of the graph of the polynomial function.

Front

What is the degree of the polynomial f(x) = x^3 - 6x^2 + 3x + 10?

Back

The degree of the polynomial is 3, which is the highest power of x in the polynomial.

Front

What does it mean for a polynomial to be factored completely?

Back

A polynomial is factored completely when it is expressed as a product of irreducible polynomials over the given number system.
