#### Abstract

Omar Bin Al-Khayyam was a Persian poet and mathematician from 1048 to 1131. Born in Nishapur, modern day Iran, Omar witnessed the fall of the Abbasid Caliphate to the Seljuk Turks, which by 1055 had conquered much of the Persian region of the Abbasid Caliphate. Omar also lived during the First Crusade in 1097. Omar was known for his mathematics which includes his proof of the quadratic formula for positive values using only geometry. This project looks at the Omar’s proof of the quadratic formula step by step to discover how Omar proved the quadratic formula for positive values.
