A polynomial is given by q

$=$

$-$

$5$

$.$

$5$

x

$^$

$2$

$-$

$2$

$.$

$0$

$.$

$$Read x from input as a float and compute q using the polynomial.

Ex: If the input is

$2$

$.$

$2$

$,$

$$then the output is:

$-$

$2$

$8$

$.$

$6$

$2$

$0$

Note:

$$x

$^$

$2$

$$can be computed using

$*$
