ব্যাখ্যা

দেওয়া আছে, $\frac{3}{x} + \frac{4}{x+1} = 2$

বা, $\frac{3(x+1) + 4x}{x(x+1)} = 2$
বা, $\frac{3x + 3 + 4x}{x^2 + x} = 2$
বা, $2(x^2 + x) = 7x + 3$
বা, $2x^2 + 2x - 7x - 3 = 0$
বা, $2x^2 - 5x - 3 = 0$
বা, $2x^2 - 6x + x - 3 = 0$
বা, $2x(x - 3) + 1(x - 3) = 0$
বা, $(x - 3)(2x + 1) = 0$

$\therefore x = 3$ অথবা $x = -\frac{1}{2}$

উত্তর: 3, -1/2
