Factoring Polynomials

Factor Completely: 3x²+15x-72

• x(x+5)
• 3(x+8)(x-3)
• (3x+24)(x-3)
• 3(x-8)(x+3)

Factor Completely: 5x²-11x+6

• (5x+6)(x-1)
• (5x-6)(x-1)
• (2x-7)(x-3)
• (5x-6)(x+1)

Solve:

x² - 4x = 21

• x = {-7, 3}

• x = {-3, 7}

• x = {3, 7}

• x = {-3,-7}

Factor the Polynomial

12x³ - 9x² + 4x - 3

• (3x² + 1) (4x - 3)

• (3x² - 1) (4x + 3)

• (4x² + 1) (3x - 3)

• (4x² - 1) (3x + 3)
