[Hacked]

How do you do problem as followed:?Dividing Polynomials
(-x^3+ 22x^2- 120x) ÷ (x - 12)

(-2x^3- 22x^2- 60x) ÷ (x + 5)

(-3x^3- 30x^2- 75x) ÷ (x + 5)

(-3x^3+ 6x^2+ 45x) ÷ (x - 5)

(-4x^3+ 20x^2+ 144x) ÷ (x - 9)

(3x^3- 27x^2+ 54x) ÷ (x - 3)

(3x^ + 9x^ - 12x) ÷ (x + 4)

(5x + 4x? - 4) ÷ (2x - 1)

(2x^3- 18x^ + 28x) ÷ (x - 2)

(x^4+ 3x^3- 8x^2+ 30x - 180) ÷ (x + 6)

Test is tommorow my overall grade depends on these..Plese help; Thank YOU!
