Question

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

Answer 1

${a}^{2} - {b}^{2} = (a + b)(a - b)$

${(a + b)}^{3} = {a}^{3} + {b}^{3} + 3 {a}^{2} b + 3a {b}^{2}$

Answer 2

Answer:

The expansion of the algebraic identity a plus b whole square can be derived in mathematical form by the geometrical approach. In this method, the concept of the areas of the geometrical shapes squares and rectangles are used in proving the a plus b whole square formula.
