Which iterative algebraic process did Al-Khwarizmi's method, 'al-jabr,' effectively apply to solve quadratic equations geometrically?

💡 Explanation

When faced with quadratic equations, Al-Khwarizmi employed a 'completion of the square' because by geometrically manipulating an equation to form a perfect square, a solution could then be derived directly via square root operations. Therefore geometric square completion arises, rather than linear programming or elimination, applicable to optimization/linear systems.
