Kylie's Math Textbook: Solving Quadratic Equation by Quadratic Formula

NOTES
$x=\frac{-b\pm\sqrt{b^2-4ac\ }}{2a}$ (QUADRATIC FORMULA)
1. Plug the a, b and c values into the quadratic equation.
2. Simplify inside the radical.
3. Simplify even more.
4. Take the square root of whatever is inside of the radical.
5. Break the equation up into 2 little ones by separating the + and - signs.
6. Solve the 2 equations and those are your answers!

PROBLEM 1

PROBLEM 2

REFLECTION
I love solving with the quadratic formula because I have the formula memorized and it is easy to plug all the numbers in a solve really quickly!
