{tex}x ^ { 2 } + \left( \frac { a } { a + b } + \frac { a + b } { a } \right) x + 1 = 0{/tex}

{tex}x ^ { 2 } + \frac { a } { a + b } x + \frac { a + b } { a } x + 1 = 0{/tex}
{tex}x \left( x + \frac { a } { a + b } \right) + \frac { a + b } { a } \left( x + \frac { a } { a + b } \right) = 0{/tex}
{tex}\left( x + \frac { a } { a + b } \right) \left( x + \frac { a + b } { a } \right) = 0{/tex}
{tex}\therefore{/tex} {tex}x = \frac { - a } { a + b } , \frac { - ( a + b ) } { a }{/tex}
