Answer
$x\approx\left\{
-1.37, 4.37
\right\}
$
Work Step by Step
The standard form of the given equation is $x^2-3x-6=0$.
Using a graphing software, the graph of the given equation is shown below.
The solutions of the equation are the $x$-values when the graph crosses the $x-$axis. Hence, based on the graph, the solutions are $
x\approx\left\{
-1.37, 4.37
\right\}
.$
