To solve the quadratic equation x2 + 10x + 12 = 0, we can use the factoring method.
First, we need to express the equation in standard form:
x2 + 10x + 12 = 0
Next, we look for two numbers that multiply to the constant term (12) and add up to the coefficient of the x term (10). The numbers 2 and 6 satisfy these conditions since:
- 2 × 6 = 12
- 2 + 6 = 10
Now we can factor the quadratic equation:
(x + 2)(x + 6) = 0
To find the values of x, we can set each factor equal to zero:
- x + 2 = 0 ⟹ x = -2
- x + 6 = 0 ⟹ x = -6
Therefore, the solutions for the equation x2 + 10x + 12 = 0 are x = -2 and x = -6.
