b, and c are coefficiencts and y and x are variables. It is easier to solve a quadratic equation when it is in standard form because you compute the solution with a, b, and c. However, if you need to graph a quadratic function, or parabola, the process is streamlined when the equa...

Factor the quadratic inside the parentheses, which is a perfect square. In y + 18 = 2(x^2 + 4x + 4), factoring x^2 + 4x + 4 yields (x + 2)^2, so the example becomes y + 18 = 2(x + 2)^2. Move the constant on the left-hand side of the equation back over to the r...

If you need to find the vertex of a parabola, however, the standard quadratic form is much less helpful.Instead, you'll want to convert your quadratic equation into vertex form. What Is Vertex Form? While the standard quadratic form isax2+bx+c=y,the vertex form of a quadratic equation ...
The vertex of a parabola is a point at which the parabola makes its sharpest turn. The vertex of f(x) = ax^2 + bx + c is given by (-b/2a, f(-b/2a)). Learn how to find vertex of a parabola from different forms like standard form, vertex form, and inter
What Is the y Intercept of a Quadratic Function? The y-intercept is where the parabola of a function crosses (or intercepts) the y axis. Another way to define the y-intercept is the value of y when x is equal to zero. Because the y intercept is a point on a graph, you'll usually...
