Math Art Visual Wonders

A close-up photo of a green blackboard. Use white chalk to write the correct derivation steps for the formula for finding the roots of quadratic equations in one variable. First row: ax^2 + bx + c = 0. Second row: x^2 + (b/a)x = -c/a. Third line: Recipe. Last line: x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}. The handwriting is neat and clear. No garbled text.

A hyper-realistic photograph of the Penrose Triangle made of polished gold rests on a marble table. This object creates a continuous, impossible triangular optical illusion. The geometric structure is not broken. Studio lighting.

A bidirectional graphic design art. If you look straight at the word, it's 'LIFE'; if you look at it with a 180-degree rotation, it's 'DEATH'. White paper and black ink, Gothic calligraphy style.
