# Write a function called quadSolver(a,b,c) that solves the quadratic equation
# ax^2 + bx + c = 0 for x. The function returns only REAL values of x, up to two
# solutions, by applying the quadratic formula.
#
# In addition, the function needs to handle exceptions such as when a = 0 and also
# when a, b, or c is a string.
#
# Use the quadratic solver (http://www.mathsisfun.com/quadratic-equation-solver.html)
# to test different values of a, b, and c. Note: This quadratic solver does not provide
# a solution for the case a = 0 but there is generally one.
