Factoring Tutorials

Solve by factoring:

3x² - 11x + 6 = 0

• x = -2/3 and x = -3

• x = -1/3 and x = 6

• x = -3/2 and x = 3

• x = 2/3 and x = 3

What is the next step in solving 
(x + 2)(x - 3) = 0      ?

• Plug in zero for x

• Solve for x

• FOIL

• Set each factor equal to zero

Solve for the values of x:
(2x + 5)(5x - 2) = 0

• { -5/2, -2/5 }

• { -5/2, 2/5 }

• { 5/2, 2/5 }

• { 5/2, -2/5 }

Finish solving by factoring:
(x - 3)(x + 6) = 0

• { -3, -6 }

• { 3, -6 }

• { -3, -6 }

• { 3, 6 }

Solve for x by factoring.
x² + 2x + 7 = 10x - 5

• x= -6, -2

• x= -2, 6

• x= 2, 6

• x= -6, 2

Solve by factoring.
x² - 2x = 0

• x = 2 and 0

• x = -2 and 0

• x = 2

• x = 0

Solve by factoring
7x² = -21x

• x = 3

• x = -3

• x = 0, 3

• x = 0, -3

Solve by factoring

• x= -4, 2

• x= -2, 4

• x= -16

• x= -4
