What is the quadratic formula?

x = (-b ± √(b²-4ac)) / (2a)

x = (b ± √(b²+4ac)) / (2a)

x = (-b ± √(b²+4ac)) / (2a)

x = (b ± √(b²-4ac)) / (2a)

How do you find the vertex of a parabola given in standard form?

The vertex can be found using the formula x = -b/(2a) for the x-coordinate, then substitute back to find the y-coordinate.

The vertex is always at the origin (0,0) of the parabola.

The vertex can be found by calculating the midpoint of the x-intercepts.

The vertex is located at the point where the parabola intersects the y-axis.
