A three-panel triptych presenting three visual reasoning concepts side by side: Panel 1: A close-up photograph of a [green chalkboard] with the derivation of the quadratic formula written in neat [white chalk]. First line: ax^2 + bx + c = 0. Second line: x^2 + (b/a)x = -c/a. Third line: completing the square. Final line: x = (-b ± √(b^2 - 4ac)) / (2a). Neat, legible mathematical handwriting with no garbled symbols. Panel 2: A realistic studio photograph of a [Penrose triangle] crafted from [polished gold], resting on a [smooth marble table].
