`Write a program to solve a quadratic equation.
`

`Write a program to approximate the exponential
by Taylor polynomials with a prescribed tolerance,
but using an order lower than or equal to a prescribed value
(when the order needed to satisfy a certain accuracy
is too high, we stop at the prescribed maximal order
and ignore the tolerance requirement).
Check program's accuracy and speed against the
intrinsic function EXP.
