Solutions:
1)
a). for \(x = 2\), solution is undefined; for \(x = -3\), solution is \(\large\frac{-14}{5}\); \(x= -6\), solution is \(\Large\frac{-41}{5}\)
b). for \(x = 2\), solution is \(\Large\frac{8}{5}\); for \(x = -3\), solution is undefined; for \(x = -6\), solution is -8
c). for \(x = 2\), solution is undefined; for \(x = -3\), solution is -1; for \(x = -6\), solution is \(\Large\frac{23}{16}\)
2). Any time there is a zero in the denominator, there is no solution for that value of x.
