Geometry was first, algebra is based on geometry.
How to prove:
(a+b)²=(a²+2ab+b²)
(a-b)²=(a²-2ab+b²)
(a+b)(a-b)=(a²-b²)
It is such simple!
Just move the Points B or D an try to detect the equivalence of the areas!
You have three formulas to learn. There is only one explained. How to get the others?
