📝8.2 CYU: Adding and Subtracting Polynomials

Simplify:
 (x + 2x²) + (4x² + 7x)

• 6x² + 8x
• 8x² + 6x
• 2x² + 6x
• 2x² + 8x

Add or Subtract to Simplify:
(4x²+ x) - (x²+ 2x)

• 3x² - x
• 4x² + 2x
• 3x² + 3x
• 3x² + 2x

Simplify the expression.
(4a³ - 8a - 4a²) + (7a³ +8a - 6)

• 11a³ - 4a² - 6

• 11a³ - 4a² + a - 6

• 11a³ - 4a² -16a - 6

• 11a³ - 4a² - a - 6

Simplify each expression. 
(4x⁴ - 3x²+6x) + 2(7x⁴ + 5x² + 8x)

• 18x⁴ + 2x² + 14x

• 18x⁴ + 7x² + 22x

• 14x⁴ + 10x² + 16x

• -10x⁴ - 13x² - 22x

Simplify the following polynomial expression.
(x² +5x- 4) - 2(-x² +4x+ 6)

• 3x² + x + 2 

• x + 2
• -x² + x - 10 

• 3x² - 3x - 16 

(x³-x²+4) - (3x³-2x²+3)

• -2x³-3x²+7
• -2x³+x²+1
• 2x³-3x³-1
• 4x³-3x²+7
