How do you convert from standard form to vertex form of a quadratic

👉 Learn how to graph quadratic equations by completing the square. A quadratic equation is an equation of the form y = ax^2 + bx + c, where a, b and c are constants. The graph of a quadratic equation is in the shape of a parabola which can either face up or down (if x is squared in the equation) or face left or right (if y is squared).
To graph a quadratic equation, we need to know some essential parts of the graph including the vertex. The vertex of a parabola is the turning point of the parabola. It is the point on the parabola at which the curve changes from increasing to decreasing or vice-versa.
Given a quadratic equation in standard form, we obtain the vertex of the equation by using the process of completing the square to rewrite the equation in the vertex form and hence extract the vertex of the parabola formed by the equation. Knowing the vertex of the graph and the parent graph, we can then apply the required transformation to obtain the required graph.

you can do it that way, what about when there is an "a" though?

[@shaunkashyap7321]

@@brianmclogan you Solve for it

[@eyualyilma9031]

@@brianmclogan i saw a video with a similar method but i dont like that way because you are supposed to use a calculator to find the vertex and you dont gain any understanding of how you got the answer, or how to do it yourself. but maybe you guys did it differently cause the video i saw used a calculator. id much prefer this method though.

[@fet6]

One of the reasons that Brian is such an excellent teacher, is that he doesn't do all the steps to one problem. He repeats the steps on multiple problems as he goes (for repetition) students learn much better this way in my experience! Kudos Brian!
