Solution
The discriminant of a quadratic equation is calculated using the formula D = b² - 4ac, where a, b, and c are the coefficients of the quadratic equation ax² + bx + c.
In the given polynomial 4x² + 4x + 1, a = 4, b = 4, and c = 1.
Substituting these values into the formula, we get:
D = (4)² - 441 D = 16 - 16 D = 0
So, the discriminant of the polynomial 4x² + 4x + 1 is 0 (Option A).
