A quadratic equation is written in the form:
$ax^2 + bx + c = 0$

In the given equation $3x^2+4x-1=0$

Where:
$a=3$
$b=4$
$c=-1$

The quadratic formula can be used to find the roots of any quadratic equation.

$x= (-b+- sqrt(b^2-4ac))/(2a)$

So I encourage you to plug in the values from this equation and simplify.

The answers should be $x = -1.54858 and x= 0.21525$
