The correct formula to find the x-coordinate of the vertex of a quadratic equation in the standard form \( ax^2 + bx + c \) is:
**B) x = −b/2a**
This formula derives from the vertex form of a quadratic function and is used to determine the axis of symmetry of the parabola represented by the quadratic equation.
