What is the sum of the roots of the quadratic equation x^2 + 4x + 4 = 0?

What is the sum of the roots of the quadratic equation x^2 + 4x + 4 = 0?

Step 1: Identify the coefficients of the quadratic equation. In the equation x^2 + 4x + 4 = 0, the coefficients are a = 1, b = 4, and c = 4.
Step 2: Use the formula for the sum of the roots of a quadratic equation, which is -b/a.
Step 3: Substitute the values of b and a into the formula. Here, b = 4 and a = 1.
Step 4: Calculate -b/a. This means you calculate -4/1.
Step 5: Simplify -4/1 to get -4.
Step 6: Conclude that the sum of the roots of the equation is -4.
