Hello Diane,

An excellent answer has been already given by Michael J., thus I am just adding couple words in regards to the computational part. Approximating the transcendental number

*as 2.7182818, the following quadratic equation in its canonical form:***e****x**

^{2}+ 8x - 2.7182818 = 0can be easily solved using online quadratic equation solver (http://examn8.com/QuadraticEquations.aspx), having two real solutions (rounded):

**x1= 0.326462966442681**

**x2= -8.32646296644268**

Pertinent to this particular problem (as commented by Mark M.), the second solution is not applicable, thus there is only one solution x1.

Hope this may help.
