Q$1.$ Recall that the solutions to the quadratic equation

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

is given by

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

and

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

$($We will ignore the case where Note that "square$-$root" is just "raise to the power of $0\mathrm{.}5".$ Therefore you can write this program using the pow $()$ function. However C$++$ provides a square$-$root function, $).$ In general, instead of pow $($x$,0\mathrm{.}5)$ you should use sqrt $(x).$

Write a program that prompts the user for double values for double variables a$,$ b$,$ and c and prints the two roots according to the above two formulas. The output must be in fixed point format with $5$ decimal places. Note that the computation of

$\sqrt[\phantom{2}]{b^2-4ac}$

appears twice, once in

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

and again in

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

Your program must compute $\sqrt[\phantom{2}]{b^2-4ac}$ only once to save CPU time. That implies that you should compute this value only once and store it in a variable for re$-$use.
