You can put this solution on YOUR website! Q: use the quadratic formula to find any x-intercepts on the graph of the equation
y=3x^2+9x-1
--------------------------------------------------------------------------
A:
Quadratic Formula:
In , a = 3, b = 9, and c = -1
Using quadratic formula
The x-intercepts are (, 0) and (, 0).

----
x = [-9 +- sqrt(81-4*3*-1)]/6
-----
x = [-9 +- sqrt(93)]/6
-----
x = [-9 +- 9.64]/6
---
x = 0.1073 or x = -3.1067
