Solve the equation.
$$\displaystyle{\frac{{{3}}}{{{2}{x}+{5}}}}+{\frac{{{4}}}{{{2}{x}-{5}}}}={\frac{{{14}{x}+{3}}}{{{4}{x}^{{{2}}}-{25}}}}$$

Step 1
Given:
$$\displaystyle{\frac{{{3}}}{{{2}{x}+{5}}}}+{\frac{{{4}}}{{{2}{x}-{5}}}}={\frac{{{14}{x}+{3}}}{{{4}{x}^{{{2}}}-{25}}}}$$
Now we simplify the above equation as,
$$\displaystyle\Rightarrow{\frac{{{3}{\left({2}{x}-{5}\right)}+{4}{\left({2}{x}+{5}\right)}}}{{{4}{x}^{{{2}}}-{25}}}}={\frac{{{14}{x}+{3}}}{{{4}{x}^{{{2}}}-{25}}}}$$
$$\displaystyle\Rightarrow{\frac{{{6}{x}-{15}+{8}{x}+{20}}}{{{4}{x}^{{{2}}}-{25}}}}={\frac{{{14}{x}+{3}}}{{{4}{x}^{{{2}}}-{25}}}}$$
$$\displaystyle\Rightarrow{14}{x}+{5}={14}{x}+{3}$$
$$\displaystyle\Rightarrow{5}={3}$$
Step 2
Which is not possible.
Since,
$$\displaystyle{5}\ne{3}$$
Therefore equation has no solution
