Question 14

Solving Quadratic Equations by Factoring

Solve the following quadratic equations by factoring. First write the equations in 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 + 9x = -20
