Create a function that solves a quadratic equation. The first line of your function should be:

function $[$x$1,$x$2]=$quadratic$\_$solver$($a$,$b$,$c$)$

The inputs are a$,$ b and c which must return all solutions such that ax$2+$bx$+$c$=0.$ Use

conditional statements for the following cases:

$$ If a and b are both equal to zero, then no solution exists.

$$ Otherwise, if a is zero, the problem becomes linear and there is only one solution.

$$ If solution is complex, assume no solution and inform the user.

$$ If a double root exists, return same solution twice and inform the user.

$$ Otherwise, return both solutions.

In any cases where there is no solution, return x$1=0$ and x$2=0$ with an error message. If there

is only one solution, set both x$1$ and x$2$ to this solution.
