Answer 2

Answer:

Euclid of Alexandria founded and wrote the algebraic identity:

(a+b)^2 = a^2 + b^2 + 2ab

Explanation:

A Persian mathematician named Muhammad ibn Musa al-Khwarizmi first wrote ways to solve linear and quadratic equations in his book "Al Muhtasar fi Hisab Al Gabr Wa I Muqabala" which was written in Arabic language. This book was later translated in to English and named as "The Compendious Book on Calculation by Completion and Balancing". The word "Algebra" was coined from this book and that is why Muhammad ibn Musa al-Khwarizmi is also called the "Father of Algebra". There are several algebraic identies to solve algebraic expression.

One such algebraic identity is,

(a+b)^2 = a^2 + b^2 + 2ab

It was Euclid of Alexandria who first wrote that formula in his book of "Elements".
