What is a polynomial equation?

Back

A polynomial equation is an equation that involves a polynomial expression, which is a mathematical expression consisting of variables raised to whole number powers and coefficients.

What is synthetic division?

Back

Synthetic division is a simplified method of dividing a polynomial by a linear binomial of the form (x - c). It is faster than long division and is used primarily for polynomials.

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

Back

If the remainder of the synthetic division is zero, then the binomial is a factor of the polynomial.

Front

What is the significance of the remainder in synthetic division?

Back

The remainder indicates whether the divisor is a factor of the dividend. A remainder of zero means the divisor is a factor.

What is the relationship between roots and factors of a polynomial?

Back

If r is a root of the polynomial f(x), then (x - r) is a factor of f(x).

Front

What is the conjugate root theorem?

Back

If a polynomial has real coefficients and a complex root a + bi, then its conjugate a - bi is also a root.

Front

What is the degree of a polynomial?

Back

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

Front

What is a zero placeholder in synthetic division?

Back

A zero placeholder is used in synthetic division to represent missing terms in a polynomial, ensuring that the degrees of the terms align correctly.

Front

How do you set up synthetic division?

Back

To set up synthetic division, write the coefficients of the polynomial in descending order of degree, and place the root (c) to the left.

Front

What is the first step in synthetic division?

Back

The first step is to bring down the leading coefficient of the polynomial.
