Concerning the denominator you can rewrite as: 2x/(x(1-5/x)) ; in this way the x cancel out and you get 2 because 5/x for x-> infinity tends to 0

Nice explanation sir !
Can you help me sir with this question?
Let f(x)=(m+1)x² +2mx +m-2
Q:what are the values of m that makes x1 and x2 two solution for f(x)=0 one of them is negative and the other is positive and x1≠x2
