Factor Completely:

x² - 17x + 72

• (x - 9)(x + 8)

• (x - 9)(x - 8)

• x(x - 3)

• (x + 9)(x + 8)

Factor Completely:

x⁴ - 9x²

• x²(x + 3)(x - 3)

• (x² + 3x)(x² - 3x)

• (x² + 9)(x - 3)(x + 3)

• x²(x² - 9)

Factor Completely:

4k² + 24k + 36

• (2k + 6)²

• (2k - 6)²

• (2k - 6)(2k + 6)

• 4(k + 3)²

Factor Completely: 5x² - 11x + 6

• (5x + 6)(x - 1)

• (5x - 6)(x - 1)

• (x - 5)(x - 6)

• (5x - 6)(x + 1)

Solve 5x² = 13x+6

• x = -3, x = 2/5

• x = -2, x = 15

• x = 3, x = -2/5

• x = 2, x = -15
