Algebraic puzzles for binomial formula
Distributivity
Algebraic puzzle: development
Simple distributivity
(a - b)²
Proof without words : a²-b²
Proof without words : a²- b²
(a+b)²=a²+2ab+b²
(a + b +c )²=a²+b²+c²+2ab+2ac+2bc
Proof without words : difference a^3 - b^3
Math is fun, magic and love :=)
Development with tiles :(ax+b) (cx+d)
x²+ax = ... = (x+a/2)²-(a/2)² (visual proof)
