# Question #bc867

##### 1 Answer

Factor it to find the zeros at

#### Explanation:

Factoring is the fastest way to find the zeros of this function.

Factor out the GCF first:

Factor the second part:

Put it all together:

The solutions/zeros/roots are where the function crosses the

x-axis, which means y=0 at those points. Set

There are two ways the product of these three terms equals zero:

If

Solve the two equations to get

These are the places that the function crosses the x-axis.

Find the vertex:

The x-coordinate of the vertex of a parabola is always at

Find the y-coordinate:

The vertex is at

Plot the vertex, plot the zeros, and draw your parabola!
