You plug in 0 for X in the equation
What is the acronym for remembering trigonometry?

When going to Vertex Form from Standard Form you do...
When going to Standard Form from Vertex Form you do...
What is the vertex formula?
y= a(x+h)2 + k
What is the standard formula?
y= x2 +bx+c
What are the steps from going standard form to vertex form?
- 1.) Split the equation into two parts: first two terms and last term
- 2.) Binomial shortcut: divide the b term in half and square it
- 3.) Undo the new c-value we just created with the original c-value
- 4.) Use the binomial short cut to write the equation in vertex form
What is the Binomial Shortcut?
example: (x+6)2 = x2 +12x+36
