1. 3.4: Vertex to Standard Form
Objectives:
• Review expanding binomials
• Change Vertex Form of a
quadratic to Standard Form

2. Mental Math Mental Math
Rewrite the expression as a power of a single variable, if possible a) ______ b) ______ c) ______

3. Concept: Squaring a Binomial
To expand (x + 6)2 you may have learned how to FOIL. (First, Outer, Inner, Last)
Recall: (x + 6)2 = (x + 6)(x + 6)
Today, I will use the “Area” method + x 6 x2 6x 36
1. Create a 2 X 2 box and
set it up as a multiplication
times table.
x2 + 6x + 6x + 36 =
2. Write out terms
3. Combine like terms
x2 + 12x + 36

4. Concept: Change to Standard Form
1. Rewrite (x+1)²
Multiply using FOIL
(or area method)
3. Don’t forget your +2
4. Combine like terms
(Standard Form)

5. Rewrite the quadratic function in standard form.
