Solve the quadratic equation by factoring

a² + 10a + 21 = 0

• ± √21

• -3 and -7

• 3 and 7

• 28 and -7

• -28 and 7

Solve the equation. 2m² + 13m +20 = 0

• m = 5/2 or m = -2

• m = -5/2 or m = 2

• m = -5/2 or m = -1

• m = -5/2 or m = -4

• m = 5/2 or m = 4

5x²-25x=5x-40

• x= -4, -2

• x= -4, 2

• x= 4, 2

Solve by factoring:  12x² + 33x - 9 = 0

• x = -3/4 and x = -1
