SUMMARY
The inequality \(\frac{4x^2}{(1-\sqrt{1+2x})^2}<2x+9\) can be solved by first recognizing that the denominator is always positive, allowing for multiplication without altering the inequality sign. By expanding the equation and isolating the square root, the problem reduces to solving a polynomial of degree 4. This approach leads to identifying the critical points and determining the intervals where the inequality holds true.
