Solving a quadratic inequality $x^2-3x-10>0$ I am solving the following inequality, please look at it and tell me whether am I correct or not. This is an example in Howard Anton's book and I solved it on my own as given below, but the book has solved it differently!  I want to confirm that my solution is also valid.


If you graph the function $y=x^2-3x-10$, you can see that the solution is $x<-2$ or $x>5$.
