How to find the vertex of a parabola in standard form
And so to find the y value of the vertex, we just substitute back into the equation. The y value is going to be 5 times 2 squared minus 20 times 2 plus 15, which is equal to let's see. This is 5 times 4, which is 20, minus 40, which is negative 20
Nice apps and its a big help to everyone to find correct answer in math problem solving, this app does have its limits as to what it can get you but if you have any basic knowledge of math it is easy to put into smaller pieces to find the whole answer.

How To Find The Vertex Of A Parabola (3 Methods To Know)
1.) Find the two zeros (roots), r and s, of the quadratic from the factored form. These value comes from the factored form y = a (x – r) (x – s). 2.) Take the average of r and s
Graphing Quadratics: The Leading Coefficient & The Vertex
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
