Question 514812: i have aother question haha im not doing my hw these are just equations i need to study for my test that i can't figure out how to solve. thanks so much for helping. this question is solve: x^2-3x-4>0 now what i did was break it down into (x-4)(x+1) so x>4 or x>-1. but i am ot sure if that is how i should right it or not Answer by solver91311(24713) (Show Source):
Change your inequality to an equation. Plot the two roots. The two roots will divide the x-axis into three intervals. Pick a value from each of the intervals that is NOT an endpoint. One or two of the values will make the original inequality a true statement. The interval or intervals from which the value(s) that make the inequality true is (are) the interval or intervals that represent the solution set of the inequality.
