Answer:-
To find the vertex of a quadratic equation in the form ???? = ???? ???? 2 + ???? ???? + ???? y=ax 2 +bx+c, use the formula ???? = − ???? / 2 ???? x=−b/2a to find the x-coordinate of the vertex. Substitute this value into the equation to calculate the corresponding y-coordinate. The vertex is the point ( − ???? / 2 ???? , ???? ( − ???? / 2 ???? ) ) (−b/2a,f(−b/2a)), which represents the highest or lowest point of the parabola, depending on whether the parabola opens upward ( ???? > 0 a>0) or downward ( ???? < 0 a<0). This method is simple and works for all quadratic equations, helping to understand their graph and properties.
