    Re: Solving inequalities

    This is very helpful but i am still stuck on a particular inequality. 2-3x<|x-3|. So far i have used the modular property and obtained a three term quadratic equation which further factorizes to (2x+1)(4x-5)<0. So according to me the answer is -1/2<x<5/4 but according to the marking scheme its only x>-1/2. Can somebody plz explain why?

    Any inequality can be written as an equation and so ax^2+bx+c\leq 0 you can write the equation as ax^2+bx+c=d\leq 0.The solutions of the inequality are :

    x=\frac{-b\pm \sqrt{b^2-4a(c-d)}}{2a} where d\leq 0.
