Solve using the Quadratic Formula: x² + 8x + 15 = 0
To solve the quadratic equation using the Quadratic Formula, we first identify the coefficients a, b, and c:
a = 1
b = 8
c = 15
The Quadratic Formula is:
Step 1: Calculate the Discriminant
First, we calculate the discriminant D:
D = 64 - 60 = 4
Step 2: Apply the Quadratic Formula
Now we substitute b, D, and a into the formula:
