Vertex of a quadratic equation

Well, when x is equal to negative two, this whole thing is zero and y is equal to negative 27. Y is equal to negative 27, so this right over here is negative 27. And so the coordinates of the vertex here are negative two comma negative 27.

How do you find the vertex of a quadratic equation?

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 = ax2

Vertex of a Quadratic Equation

A quadratic equation is written as ax2 + bx +c in its standard form. And the vertex can be found by using the formula − b 2a. For example, let's suppose our problem is to find out vertex (x,y) of the quadratic equation x2
