Classifying, Adding, Subtracting, Multiplying Polynomial

What is the degree of the following polynomial?

3x² + 2x³ + 5x⁵ ?

• 1
• 10

• 5

• 4

What is the leading coefficient of the polynomial?
  7x⁵ - 9x² + 6x

• 7

• 5

• 9

• 2

Multiply: (x + 5)(x + 4)

• x² + x + 20

• x² + 20x + 9

• x² + 9x + 20

• x² - 9x + 54

You can FOIL to multiply polynomials...

• When you have 2 binomials

• Any time

• When you have a monomial

• When you have only 1 binomial

Write the polynomial in descending order:

 9x² + 5x + 27 + 2x³

• 27 + 5x + 9x² + 2x³

• 9x² + 5x + 2x³ + 27

• 9x² + 5x + 27 + 2x³

• 2x³ + 9x² + 5x + 27

How can you rewrite (2x+3)² to multiply easier?

• 4x²+9

• (2x+3)(2x+3)

• 4x+6

• 2(2x+3)

What is (3x² + 2x - 6) - (2x² - 3x + 1)

• x² + 5x + 5

• x² - 5x - 7

• x² + 5x - 7

• x² - 5x + 7

Combine like terms: 8x³y + 3x²y + 4xy + 5x²y + 2xy + 7x²y

• 8x³y + 8x²y + 2xy

• 11x³y + 15x²y + 8xy

• 8x³y + 15x²y + 6xy

• 23x²y + 6xy

Classify the polynomial by degree and number of terms:

• Cubic Trinomial

• Cubic Binomial

• Quadratic Trinomial

• Quadratic Binomial

• Polynomial

• Non-Polynomial
