The standard form of the equation for a parabola is y = ax^2 bx c. A parabola is the set of all points in a plane that are equidistant from a given line and a given point not on the line. More »

The standard form of a quadratic equation is y = ax^2 bx c, so you may need to move terms around to make the equation take this form. A quadratic equation might be written in the vertex form, which is y = a(x - h)^2)... More »

To find the vertex of a parabola, put the terms of the standard parabola equation into vertex form. The standard equation is y = ax^2 bx c. The vertex form is y = a(x - h)^2 k. The vertex of the parabola is at poin... More »

The vertex form of a quadratic equation is written like f (x) = a(x - h)2 + k, with the letter h and the letter k being the vertex point of the parabola. It can be used to create an equation when the vertex of the parabo... More »

To find the vertex of a parabola, put the terms of the standard parabola equation into vertex form. The standard equation is y = ax^2 + bx + c. The vertex form is y = a(x - h)^2 + k. The vertex of the parabola is at poin... More »

The directrix of a parabola refers to a straight line that is drawn perpendicular to the axis of symmetry of a parabola. This line does not touch the parabola at any point. In addition, it is a horizontal line if the axi... More »

To solve the quadratic equation ax^2 + bx + c - 0, plug the corresponding numbers into the quadratic formula. Take the opposite of b, and provide the option of adding or subtracting the square root of (b^2 - 4ac). Divide... More »
