 \frac{1}{2a + b + 2x} =  \frac{1}{2a} +  \frac{1}{b} +  \frac{1}{2x}


 \frac{1}{2a + b + 2x} -  \frac{1}{2x} =  \frac{1}{2a} +  \frac{1}{b}


 \frac{2x - 2a - b - 2x}{(2x)(2a+b +2x) }=  \frac{b + 2a}{2ab}


 \frac{-1(2a+ b)}{(2x)(2a +b + 2x)}  = \frac{b+ 2a}{2ab}


 \frac{-1}{(2x)(2a+b+2x)} =  \frac{1}{2ab}

                       Cross Multiply 

⇒ -2ab = (2x)(2a + b+ 2x)

-2ab = 4ax + 2xb + 4x^2

⇒ 0= 4ax + 4x² + 2xb + 2ab

⇒ 0=  4x(a + x) + 2b(x + a)

⇒ 0= (x + a) (4x + 2b)

                             By Zero Product Rule

⇒ x + a = 0    OR   4x + 2b = 0

⇒ x= -a    OR     4x = -2b

⇒ x = -a   OR    x =  \frac{-2b}{4} =  \frac{-b}{2}



i hope this will help you
