Question

plzz solve this que.....

Answer 1

$\frac{1}{x + 1 } + \frac{1}{x + 2 } = \frac{2}{x + 10}$
$\frac{x + 2 + x + 1}{(x + 1)(x + 2)} = \frac{2}{x + 10}$
$\frac{2x + 3}{ {x}^{2} + 2x + x + 2} = \frac{2}{x + 10}$
$(2x + 3)(x + 10) = {2x}^{2} +4x+ 2x+4$
${2x}^{2} + 20x + 3x + 30 = {2x}^{2} + 6x + 4$
$23x + 30 = 6x + 4$
$23x - 6x + 30 - 4 = 0$
$17x + 26 = 0$
$x = \frac{ - 26}{17}$
