Solve by Factoring and Square Root

Factor and Solve: Remember the two numbers you choose when factoring, are not your solutions to the equation!

x² + 13x + 12 = 0

• x = −12, −1

• x = 12, 1

• x = 13, 1

• x = −13, −1

Factor and solve:

z² − 14z + 45 = 0

• z = 1, 45

• z = −1, 45

• z = −5, 9

• z = 5, 9

• 2(x + 4)(x - 2) = 0;   x = -4, 2

• 2(x + 8)(x - 2) = 0;   x = -8, 2

4x²+7x-17=3x²+12x-3

• x= -7, -2

• x= 7, -2

• x= -7, 2

3x²+9x-30=0

• x= 2, -5

• x= 5, -2

• x= -5, -2

6x²-x-2=0

• x= -2/3, 1/2

• x= 2/3, -1/2

• x= -2/3, -1/2

x²-7x=0

• x= 0, -7

• x= 0, 7

3x²-48=0

• x= 4, 4

• x= -4, -4

• x= -4, 4
