Hello, I'm new to this forum but I thought it may be helpful to come here for responses when a teacher/classmate is unavailable. I'm currently studying AS level mathematics... Ok so for the homework I have been solving quadratic inequalities by graphing them but this one question out of 10 is a problem for me. The inequality is: x^2 + 2x -1 < 0 I tried factorising it like all the others but it won't factorise so I don't know what coordinates to use to plot it on a graph and therefore can't find the solution. I also tried completing the square to get (x + 1)^2 -2 < 0 and this told me that the line of symmetry of the curve is at x = -1 and that the turning point is at -2 but this didn't help either. Can anyone explain how to do this? Any response will be appreciated.
