1. solve the following quadratic equation by factoring. Show all work and check your answer.

x^2 + 3x - 4 = 0

x = - 4, x = 1

Step-by-step explanation:

x^2 + 3x - 4 = 0

4 and - 1 add to 3 and multiply to - 4.

(x+4) (x-1) = 0

Separate these by the Zero Product Property.

x+4 = 0

x-1 = 0

Solve.

x = - 4

x = 1
