## What is the shortcut to find the roots of a quadratic equation?

**2 Answers**

- 1) a+b+c0 then the roots are 1 and c/a. Example: 33x2u221241x+80 has 1 and 8/33 as solutions.
- 2) ba+c then the roots are u22121 and u2212c/a. Example: 1793×2+2016x+223 has u22121 and u2212223/1793 as roots.
- 3) for x2+bx+c0 I test the divisors of c. If one of them say u03b1 is a root then c/u03b1 is a root.
