Answer
Quadratic Formula:
$\frac{-b+/-\sqrt {b^2-4ac}}{2a}$
$x=-3(+/-)\sqrt {10}$
Work Step by Step
The formula for the average quadratic equation is given above.
$a=1$ (your $x^2$ coefficient)
$b=6$ (your $x$ coefficient)
$c=-1$ (the lone number)
Plug in these values for $a, b, c$.
$\frac{-6+/-\sqrt {6^2-4(1)(-1)}}{2(1)}$
$\frac{-6+/-\sqrt {40}}{2}$
$\frac{-6(+/-)2\sqrt {10}}{2}$
$x=-3(+/-)\sqrt {10}$
