```							Dear Kunal If you plug in the origin we get 1=0, which is not true but 1> 0, so we need to solve the inequality a^2x+aby+1> 0 Now I want the point (1,1) to also work a^2+ab+1> 0 Solving for b b>(-1-a^2)/a For b> 0 we require that a  Hence b belongs to (0, 2) RegardsArun (askIITians forum expert)
