Factoring Practice

r² + 19r + 90

• (r - 1)(r - 5)
• (r + 9)(r + 10)
• (r + 15)(r + 6)
• (r - 9)(r - 10)

6n² - 48n + 72

• 6(n - 6)(n - 2)
• 6(n - 6)(n + 2)
• (n - 6)(n - 2)
• 6(n + 6)(n - 2)

5v³ - 10v² - 15v

• 5v(v + 1)(v - 3)
• 5v(v + 1)(v + 3)
• 5(v + 3)(v - 1)
• 5v(v - 1)(v - 3)

9x² - 6x - 80

• (3x + 8)(3x - 10)
• (2x - 9)(2x - 3)
• (3x + 2)(3x - 40)
• Not factorable

b² + 6b - 40

• (b + 2)(b - 20)
• (b - 4)(b - 10)
• (b + 40)(b - 1)
• (b - 4)(b + 10)

a² - 4

• (a + 2)(a - 2)
• (-a + 2)(a - 2)
• (a - 2)2
• (3a + 2)(3a - 2)

5a² + 16a - 16

• (5a + 4)(a + 4)
• (5a + 4)(a + 4)

• (5a - 4)(a + 4)

2n² + 5n

• n(2n - 5)
• n(2n + 1)
• 2n(n + 5)
• n(2n + 5)

x² + 4x - 5

• (x - 1)(x - 5)
• (x + 1)(x - 5)
• (x - 1)(x + 5)
• (x - 7)(x - 8)

r² - 9
