Solving Quadratics

2. Warm-up
Factor:
1) 2)

3. Standard Form for a Quadratic
Where a,b, and c are real numbers, and a does not equal zero.
Example:
We’re going to solve this by factoring!

4. Zero product property If AB=0, then A=0 or B=0
So if (x+1)(x – 5) = 0, then…
x + 1 = or x – 5 = 0
These x-values represent ________________ on the graph of the quadratic function.

5. Solve by Factoring First, get the function in STANDARD FORM.
Then, use the “ac that adds to b” method to find the x – intercepts for the quadratic function.

6. You try!
Solve by factoring.
