Solving Quadratic Equations by Factoring

Solve the following quadratic equations by factoring. First write the equations

completely factored form. Then write the real number solutions.

[Hint: Remember to use proper notation when writing the real number solutions. For

example: if the solutions are x = 1 and x 4, write x =

=

1,4

x² + 11x = -30

Factored Form

X = -5,-6

Real Number Solutions

- x² – 2x = 0

Factored Form

X = -2,0

Real Number Solutions

x² - 20 =

= X

Factored Form

X = 5,-4

Real Number Solutions

-3x² = 6x

Factored Form

X = -2,0
