If a, b, c are positive real numbers, then the number of of real roots of the equation ax2+ b|x|+ c = 0 is
f(x)=a|x|2+ b|x|+ c so the graph of of above function always lies above xaxis because a,b,c are positive and mod x is also positiveso their sum and product will be positive so it can never become 0 so no real rootsPLEASE APPROVE
