समीकरण सोडवा: \frac{1}{x+5} =\frac{1}{x^{2} } (x\neq0, x+5\neq0)\\

\frac{1}{x+5} =\frac{1}{x^{2}} \\ \\ {x}^{2} = x + 5 \\ \\ {x}^{2} - x - 5 = 0 \\ \\

x_{1,2} = \frac{ - b ± \sqrt{ {b}^{2} - 4ac} }{2a} \\ \\ x_{1,2} = \frac{ - ( - 1)± \sqrt{ {( - 1)}^{2} - 4(1)( - 5)} }{2(1)} \\ \\x_{1,2}= \frac{ 1 ± \sqrt{ 1 + 20} }{2} \\ \\ x_1 = \frac{1 + \sqrt{21} }{2} \\ \\ x_2 = \frac{1 - \sqrt{21} }{2} \\ \\
