To find the vertex of a quadratic equation, y = ax2 + bx + c, we find the point (- b / 2 a, a (- b / 2 a) 2 + b (- b / 2 a) + c ), by following these steps. Get the equation in the form y =

Using the Vertex Formula 1. Identify the values of a, b, and c. In a quadratic equation, the term = a, the term = b, and the constant term (the 2. Use the vertex formula for finding the x-value of the vertex. The vertex is also the equation's axis of symmetry. 3. Plug the value into the original See more

The quadratic formula is: x = −b ± √b2 − 4ac 2a x = - b ± b 2 - 4 a c 2 a You can use this formula to solve quadratic equations. Or, if your equation factored, then you can use the quadratic formula to test if your solutions of the quadratic
