The roots of a quadratic equation

$a{x}^2+bx+c=0$

are given by the formula

$x=\frac{-b+-\sqrt[\phantom{2}]{b^2-4ac}}{2a}$

Write a function that takes in the coefficients of a quadratic equations $a,b$ and

$c,$ then calculates the roots $x1$ and $2$ of the equation using the formula above.

Your program should check that $a0$ and $b^2>4ac.$ If print the

statement $"$No real solution".

For example, the roots of the quadratic equation $x2-7x+10=0$ are $x=2$ and

$x=5$

Note: Some of parameters must be passed as a reference.
