The **general form** of a quadratic equation is *
y* =

For example,

The **factored form** of a quadratic equation is *
y* =

For example,

The factored form is useful because we can see the

For example, the

The **vertex form** of a quadratic equation is *
y* =

For example,

The vertex form is useful because we can see the turning point or vertex of the graph.

For example, the turning point or vertex of
