I understand that in algebra inequalities one side has to be made zero but in the equation shown above, I am unable to find the set of values that satisfies the equation.
well, we know that < 0 means it is negative, correct? and if the numerator of a fraction is positive, the only way to make it negative is if we make the denominator negative.
now, 1 is a positive number, therefore, to make the fraction , we must have that
so now, your problem is actually to solve this last inequality. treat the < sign as an equal sign at first and solve (you keep writing "<" but treat it as if it were "="); then make sure the interval solutions you choose for your x-values make the solution set negative.
