What are the advantages of the new improved Quadratic Formula in graphic form?
Improved Quadratic Formula
Improved Quadratic Formula in Graphic Form (Google, Yahoo, Bing Search). It can be also called "The Quadratic Formula in intercept form"
Compared to the classical formula, the advantages are:
a. Simpler expression
b. Easier numeric computation, there for, less errors/mistakes.
c. Systematic steps to proceed.
d. Shows graphic interpretation and relationship between:
- The axis of symmetry and the 2 x-intercepts, and
- The distances from the axis of symmetry to the two x-intercepts.
Example of solving.
There are 2 real roots:
