Addition Subtracting and Multiplying Polynomials

To subtract polynomials, we ____ the _________ by distributing a ____.

(USE YOUR NOTEBOOK)

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

• x² + 5x + 5

• x² - 5x - 7

• x² + 5x - 7

• x² - 5x + 7

Find the sum.
(3x³ + 3x² – 4x + 5) + (x³ – 2x² + x – 4)

• 4x³ + 1x² – 3x + 1

• 2x³ + 1x² - 5x + 9

• 6x³ + 1x - 1x² - 3

• 3x⁵ +1x - 1x⁵ - 3x

Add: (3x - 2) + (3x² + 6x)

• 3x² + 9x - 2

• 6x² + 4x

• 3x² + 3x - 2

• 6x² + 6x - 2

What is (4n² - n + 3) + (n² + 5n - 2)

• 3n² + 6n - 5

• 3n² - 6n + 5

• 3n² + 6n + 5

• 3n² - 6n - 5
