# Solving Quadratic Equations

#### Posted February 29, 2012

#### by Lensyl Urbano

So here we have a little grapher that solves quadratic equations visually. Just**enter the coefficients in the equation**. Quadratic Equation:

`y = a x`

^{2}+ b x + c
Enter:
y =
x^{2} +
x +

# Solution:

Analytical solution by factoring (with a little help from the quadratic equation if necessary).

Hopefully, this can help students learn about factoring and quadratics in a more graphical way.

## Notes:

This is my first interactive post. I use Javascript in combination with HTML5. Now I need to figure out how to interact with the image itself, instead of the textboxes.**Citing this post**: **Urbano**, L., 2012.
