The equation is
.
The standard form of quadratic equation in x - variables is
, where
.
Graph the related function
to the equation
.

Observe the graph, the graph intersect to the x - axis at two points. So the equation has two solutions. The graph intersect to the x - axis at points are
. So the solutions are
.
To check the first solution, the values of
substitute in the original equation,
.
