Adding/Subtracting/Multiplying Polynomials & Exponent Rules

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

Add to Simplify:
 (4x - 2x³) + (5x³ - 4x + 5)

• 3x³ + 5
• 3x³ + 8x + 5
• 3x² + 5
• 7x³ + 8x + 5

(4n⁴ - 8n + 4) - (8n² + 4n⁴ + 1)

• -8n² - 8n + 3

• -7n² - 8n + 3

• -6n² - 8n + 3

• -7n² - 4n + 3

(4q⁴ - 9q) - (6q + 8q⁴)

• 4q⁴ + 15q
• -4q⁴ - 15q
• -4q⁴ - 3q
• 4q⁴ + 3q

(3n-4)(3n-4)

(8m-2)(8m+2)

Simplify:
2x ( -2x -3)

• -4x - 3
• x² - 3
• -4x² - 6x
• -4x - 6

 2x³(x²−2x − 3)

• 2x⁶- 4x³ - 6x³
• 2x⁵−4x⁴ − 6x³
• -2x⁵−4x⁴ − 6x³
• -2x⁶−4x³ − 6x³
