Adding and Subtracting Polynomials

Add the following polynomials:
 (5x + 2) + (4x + 5)

• 9x -7
• -9x-11
• 9x+7
• x+7

Add the following polynomials:
(6n² - 7n⁴+8) +  (6 + 8n + 4n⁴)

• -3n⁴+ 6n²+8n+14
• -n⁴-2n²+8n+7
• -n⁴ + 6n²+8n+7
• -3n⁴+ 6n²+8n+7

(3x² + 4x - 2) - (5x + 7)

• 3x² - x - 9
• 2x² - 9
• 3x² + 9x - 5

• 12x⁴ + 2x² + 3
• 2x² - 4x - 3

Combine (3x - 4) + (12x + 10)

• x - 12

• 15x + 6

• 36x + 40

• 17x + 9,000

Simplify (9x + 17) + (19x - 27)

• 28x + 44

• 28x - 10

• -28x + 10

• -171x - 459

Add the polynomials.
