Question

Geometrical proof of a^2-b^2,
And geometrical proof of (a+b)^3.​

Answer 1

Answer:

Take a square, whose length of each side is a units. Therefore, the area of the square is a²  

.

Draw a small square with the side of b units at any corner of the square. So, the area of small square is  b²

.

Now, subtract the square, whose area is  b²

from the square, whose area is  a²

. It forms a new geometric shape and its area is equal to  a²-b²

.
