The number of real roots of the equation A2/x + B2/(x-1) = 1, where A and B are real numbers not equal to zero simultaneously is Choose the correct choice from the following options:
A) None	B) 1	C) 2	D) 1 or 2	E) 3
Explanation :   =&gt; A2/x + B2/(x-1) = 1,   =&gt; A2 (x-1) + B2x = x2 - x.   This is a quadratic equation.   Hence, number of roots = 2 or 1 (1 in the case when both roots are equal )   Nonenswer : None
