Add and Subtracting Polynomials

When adding or subtracting polynomials we add / subtract the _____________________________.

• Exponents

• Polynomials

• Coefficients

• All of the above

(3x + 4y - 3z) - (2x - 6y + 7z)

• x + 10y - 10z

• -x +10y - 10z

• x -10y - 10z

• -x -10y - 10z

Add the polynomials.
(2x + 5y) + (3x - 2y)

• 3x + 5y

• 5x + 3y

• 5x + 7y

• 7xy + 1xy

Add the polynomials.
(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

Add: (3x² + 2x + 1) + (2x² - 4x - 5) + (3x - 1)

• 5x² + 6x - 7

• 8x² - 3x - 5

• 5x² + x - 5

• 6x² + 8x + 5

Add or Subtract to Simplify:
(5x + x² - 4) - (4x - x² + 6)

• 2x² + x + 2 

• x + 2

• 2x² + x - 10 

• x - 10 

What is (5x²-2x-4) + (x² - 2x + 3)

• 6x² - 4x - 1

• 6x² + 4x + 1

• 6x² - 4x + 1

• 6x² + 4x - 1

What is (-2y² + 7y - 1) + (3y² - 5y + 9)

• y² - 2y + 9

• y² + 2y - 9

• y² - 2y + 8

• y² + 2y + 8

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

• x² + 5x + 5

• x² - 5x - 7

• x² + 5x - 7

• x² - 5x + 7
