If the quadratic equation x^2 + 2x + 1 = 0 is solved, what is the nature of its roots? (2019)

If the quadratic equation x^2 + 2x + 1 = 0 is solved, what is the nature of its roots? (2019)

Step 1: Identify the coefficients of the quadratic equation x^2 + 2x + 1 = 0. Here, a = 1, b = 2, and c = 1.
Step 2: Use the formula for the discriminant, which is D = b^2 - 4ac.
Step 3: Substitute the values of a, b, and c into the discriminant formula: D = 2^2 - 4*1*1.
Step 4: Calculate 2^2, which is 4.
Step 5: Calculate 4*1*1, which is also 4.
Step 6: Now, subtract the two results: D = 4 - 4 = 0.
Step 7: Interpret the result of the discriminant. Since D = 0, this means the roots are real and equal.
