Solving for the Quadratic Formula
Standard Form:
Completing the Square:
- Take out "a"
- Divide "b" by "2a", square it, and then add "b/2a^2" to both sides to make it a complete square
- Simplify the completed square
- Subtract "c" from both sides
Solve for "x"
- Square "b/2a" and divide both sides by "a" to leave "(x+b/2a)^2" by itself
- Find the square root of both sides to get rid of the square
- Find the common denominator for the right side of the equal sign
- Find the square root of the common denominator
- Subtract "b/2a" from both sides to leave "x" by itself

When I tried to solve the quadratic formula I couldn't figure out the steps I was suppose to follow to figure out the answer. Some of my class mates were having the same problem as I so we decided to work as a group. It was challenging, but at the end we found the answer working as a group. I am really happy that I figured out how to solve this because it will be useful in college since I will be able solve a lot of problems using this formula. The quadratic formula can also be used to figured out when an object hits the floor after it has been thrown to the air and many more similar examples.
