Question

pls help me friends and give me genuine answer​

Answer 1

Step-by-step explanation:

We have,

$\frac{1}{a + b + x} = \frac{1}{a} + \frac{1}{b} + \frac{1}{x}$

$\implies\frac{1}{a + b + x} - \frac{1}{x} = \frac{1}{a} + \frac{1}{b}$

$\implies\frac{x - a - b - x}{(a + b + x)x} = \frac{a + b}{ab}$

$\implies\frac{-( a + b) }{(a + b + x)x} = \frac{a + b}{ab}$

$\implies - ab = ax + bx + {x}^{2}$

$\implies \: x(x + b) + a(x + b) = 0$

$\implies(x + b)(x + a) = 0$

$\implies \: x = - b \: \: or \: \: x = - a$
