Introduction to polynomials-vocabulary

Which function have you not studied this year?

• Quadratic

• Polynomial

• Linear

Before we really talk about polynomial functions, you need to learn some basic polynomial skills. Today, you are going to learn some vocabulary. Read everything carefully.

Let's start with the word monomial. A monomial is a PRODUCT of numbers and variables, such as 6ab³. Which of the following would be a monomial?

• 3x⁴

• 4x + 3

• 2x - 4y³ + 6

• 4 - x²

Again....Which of the following is a monomial?

• x⁴y

• 4 + 3x + 6x³

• 2b - c³ + 6d

• 2x - x²

One more...which of these is NOT a monomial?

• 5x

• 4

• 3x² + 5x

• 10ab⁴

A binomial is created when you add or subtract TWO monomials, such as 2x + 5. Which of the following is a binomial?

• 2x + 5 - 7x²

• b²c

• 3 - 4a

• 4 + 7a⁴ + 3x - 2b

Try that again. Which of the following is a binomial?

• 2x + 5 - 7x²

• b²c - 8

• 3 - 4a + 5b

• b - a⁴ + 9x - b²

Try that again. Which of the following is a binomial?

• 2x + 6x²

• b²c + c + 3b

• 3 - a² + 5b³

• v - a⁴ + w - 2v²

A trinomial is created by adding or subtracting three monomials, such as 3 + 2x - b⁴. Which of the following are trinomials?

• x + 9x²

• 6 - 5x + b

• 7a

• 4 - x³

Which of the following are trinomials?

• x - 8y + 2x²

• 1 - 5m

• 7xy²

• 4x + 2y - 5 - x³
