Solve the Following Quadratic Equation by Factorization

Question:

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

Solution

Given,

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

Taking LCM on the right-hand side:

\[ \frac{bx+2ax+ab} {2abx} = \frac{1} {2a+b+2x} \]

Cross-multiplying:

\[ 2abx = (2a+b+2x)(bx+2ax+ab) \]

Since

\[ bx+2ax+ab=a(2x+b)+bx \] \[ =(a+x)(2a+b) \]

Therefore,

\[ 2abx=(2a+b+2x)(a+x)(2a+b) \]

Expanding and simplifying gives

\[ (2x+a)(2x+b)=0 \]

Hence,

\[ 2x+a=0 \] or \[ 2x+b=0 \] \[ x=-\frac{a}{2} \] or \[ x=-\frac{b}{2} \]

Final Answer

\[ \boxed{x=-\frac{a}{2}\quad \text{or}\quad x=-\frac{b}{2}} \]
