Answer:
x = 1 or x = -3
Step-by-step explanation:
Solve for x:
x^2 + 2 x - 3 = 0
The left hand side factors into a product with two terms:
(x - 1) (x + 3) = 0
Split into two equations:
x - 1 = 0 or x + 3 = 0
Add 1 to both sides:
x = 1 or x + 3 = 0
Subtract 3 from both sides:
Answer: x = 1 or x = -3
