Simplify:
(3y² + y³ - 5) + (4y² - 4y + 2y³ + 8)

• 3y³ + 7y² - 4y + 3
• 4y² + 3y³ - y + 3
• -y⁴ + 2y³ - y - 4
• 4y³ + 3y² - 3y + 1

Simplify:
(3x – 1)(x + 5) 

• 3x² + 4x + 5
• 3x² + 4x - 5
• 3x² + 14x + 5
• 3x² + 14x - 5

Find the sum.
(5x² -3x + 4) +     (6x -3x² - 3)

• 3x² + 2x + 1
• 2x² + 3x +1
• 2x² + 5x - 7
• 3x² + 4x⁵ -7x

Find the difference. 
(3- 2x + 2x²) -     (4x -5 +3x²)

• x_² + 6x + 8
• 2x² + 5x - 7
• -x² -6x + 8
• -2x² + 11x - 4

Simplify the expression.
-3x²( 7x² - x + 4)

• -21x⁴ + 3x³ -12x²
• 7x² - x + 4 (-3x²)
• 21x⁴ + 3x³ + 12x²
• -12x² + 3x³ -21x⁴

(5x+2)(x²-3x+6)

• 5x³ - 17x² +24x +12
• 5x³ + 17x² - 24x +12
• 5x³ - 13x² + 24x +12
