The image captures a close-up, top-down view of a page from a light-colored, lined notebook, located in Quetta City Tehsil, Pakistan. The page is filled with handwritten mathematical equations and their solutions, rendered in dark blue or black ink, likely from a ballpoint pen. The writing is oriented vertically on the page, indicating the notebook was rotated 90 degrees clockwise relative to the camera's perspective. A distinct red vertical margin line is visible along the left side of the page. The mathematical content primarily involves algebra, specifically focusing on the factorization of polynomials and expressions incorporating complex numbers. Examples include the factorization of `z^2 + 121`, `z^2 - 9`, `z^2 + 196`, and `z^2 + 3`, with various solution steps demonstrating the application of the difference of squares formula (`a^2 - b^2 = (a-b)(a+b)`) and the imaginary unit `i` (where `i^2 = -1`). No individuals, writing instruments, or other extraneous objects are present within the photographic frame, beyond the notebook page itself.
