I was unclear if you needed this solved in vertex or standard form, so I gave you both.

Vertex form: (x - 4)^2 - 1

Standard form: x^2 - 8x + 15

Step-by-step explanation:

This is a quadratic equation. In order to solve this problem, you will need these equations:

Vertex form: a(x - h)^2 + k

Standard form: ax^2 + bx + c

Starting with vertex form:

The vertex is (4, -1). When putting this into your equation, substitute the "x" value for h, and substitute the "y" value for k.

a(x - 4)^2 - 1

You can disregard the "a" for this particular problem because it is equal to 1.

Standard form:

Now that you have vertex form, you can expand it into standard form.

(x-4)^2 - 1

Use the FOIL method to multiply (x - 4)(x - 4).

This will equal x^2 - 8x + 16 .

Keep in mind that you still have a -1 from your original equation to take into account. Once you subtract 1, this will leave you with:

x^2 - 8x + 15
