• 4

Subtract. \[ (6y^2 - 3y + 4) - (3y^2 - 3y + 6) \] (Simplify your answer. Do not factor.) \[ (6y^2 - 3y + 4) - (3y^2 - 3y + 6) = \]

• 3y^2 - 2

• 3y^2 + 2

• 9y^2 - 2

• 3y^2 - 10

Perform the indicated operation. \[ (7x^3 - 11x + 12) + (7x^3 + 8x + 8x) \] (Simplify your answer. Do not factor.) \[ (7x^3 - 11x + 12) + (7x^3 + 8x + 8x) = \]

• 14x^3 + 5x + 12

• 14x^3 - 3x + 20

• 14x^3 + 16x + 12

• 14x^3 - 11x + 20

Use synthetic division to divide. (y⁴ - 81) ÷ (y + 3) =

• y³ - 3y² + 9y - 27

• y³ + 3y² + 9y + 27

• y³ - 3y² - 9y + 27

• y³ + 3y² - 9y - 27

Divide by synthetic division. (b⁵ + 3b⁴ - 12) ÷ (b + 1) =

• b⁴ + 2b³ - 2b² + 2b - 2

• b⁴ + 3b³ - 3b² + 3b - 3

• b⁴ + 4b³ - 4b² + 4b - 4

• b⁴ + 5b³ - 5b² + 5b - 5

Use synthetic division to divide. (16x³ + 31x² - 18x + 1) ÷ (x - 1/16) =

• 16x² + 32x + 1

• 16x² + 31x + 1

• 16x² + 30x + 1

• 16x² + 29x + 1
