What is polynomial division?

Back

Polynomial division is the process of dividing a polynomial by another polynomial, similar to long division with numbers. It can be done using long division or synthetic division.

What is synthetic division?

Back

Synthetic division is a simplified form of polynomial division that is used when dividing by a linear factor of the form (x - c). It is faster and requires less writing than long division.

In synthetic division, what does the left-hand box represent?

Back

The left-hand box represents the value of c in the divisor (x - c). For example, if dividing by (x - 2), the left-hand box would contain 2.

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 2x³ - 5x² + 3x + 7, the degree is 3.

What is a remainder in polynomial division?

Back

The remainder is what is left over after dividing one polynomial by another. It can be expressed as a fraction of the divisor.

How do you check your work after polynomial division?

Back

You can check your work by multiplying the quotient by the divisor and adding the remainder. The result should equal the original polynomial.
