Topic/Objective: Factoring/ Quadratics

Name:
Class/Period: 2
Date: 12/09/15

Essential Question: How can I solve quadratics using the factoring method?

Questions:

Why does
The equation
Need to be in
Standard form to
work?
What if the
Multiples are not

Notes:
To solve a Quadratic equation using factoring
1) Set equation into standard form
a
...
Ensure equation equals zero
2) Find the number which:
a
...
And Adds to “B”

Adding to b?
How do I find all the
Factor on the chart?
How does the
Equation factor?

i
...
Example:
3) Plug in factors for “bx”
a
...


Why do I set each
Parenthesis to zero?

𝒂𝒙 𝟐 + {𝒇𝒂𝒄𝒕𝒐𝒓 𝟏}𝒙 {𝒇𝒂𝒄𝒕𝒐𝒓 𝟐}𝒙 + 𝒄

20
1 20
2 10
4 5

𝒂𝒙 𝟐 + {𝒇𝒂𝒄𝒕𝒐𝒓 𝟏}𝒙 {𝒇𝒂𝒄𝒕𝒐𝒓 𝟐}𝒙 + 𝒄

(outside factors)(inside factors) = 0

Summary: The real world applications of quadratics range from measuring force in
science to money in finances
...
They can show the path of a projectile for ballistic engineers, or the fuel
consumed during a flight for aerospace engineers
...
By solving these equations an engineer can predict how much fuel they
need in a plane or the optimum trajectory to launch to hit a specific target
