To solve the quadratic equation x² + 2x − 3 = 0, we can use the factoring method.
Step 1: Factor the Equation
We need to find two numbers that multiply to -3 (the constant term) and add up to 2 (the coefficient of x). The numbers 3 and -1 fit this requirement.
Step 2: Rewrite the Equation
Using these numbers, we can factor the equation as follows:
- (x + 3)(x - 1) = 0
Step 3: Solve for x
Now, we set each factor equal to zero:
- x + 3 = 0 → x = -3
- x - 1 = 0 → x = 1
Final Solutions
The solutions to the equation x² + 2x − 3 = 0 are:
- x = -3
- x = 1
