Factor completely.
k² -2k - 24

• (k+4)(k-6)
• (k+4)(k+6)
• (k+6)(k-1)
• (k-4)(k+6)

Factor completely:
 3x² + 5x - 12

• (3x + 4)(x-3)
• (3x - 4)(x + 3)
• (3x + 3)(x -4)
• (3x - 3)(x + 4)

Factor:
x² + 7x - 30

• (x + 10)(x - 7)
• (x - 10)(x + 3)
• (x + 10)(x + 3)
• (x + 10)(x - 3)

Solve by factoring: x² - 7x + 10 = 0

• x = 5 and x = 2

• x = -5 and x = -2

• x = -5 and x = 2

• x = 5 and x = -2

Solve for x: (x - 5)(4x + 7) = 0

• x = 5 and x = -4/7

• x = -5 and x = 4/7

• x = 5 and x = -7/4

• x = -5 and x = 7/4

Factor
k²+7k+10

• (k+2)(k+5)
• (k-2)(k-5)
• (k+10)(k+4)
• (k+2)(k-5)

Factor

• (3v-7)(v+1)
• 3(v-7)(v-1)
• (3v+1)(v-9)
• (3v+1)(v-10)

Solve
a² + 10a + 21 = 0

• ± √21
• -3 , -7
• 3 , 7
• 28 , -7

Solve
