It is interesting to represent Algebraic Identities using Geometric objects. One easy example is presented in this video.

# Think!

Try to *draw *the following algebraic identities using geometric objects

- \(a^2 – b^2 = (a+b)(a-b) \)
- \( (a+b)^3 = a^3 + 3a^2 b + 3 ab^2 + b^3 \)
- \( 1 + 2 + … + n = \frac {n(n+1)}{2} \)
