Question

Geometrically derive the formula for (a+b)² and (a-b)².

Answer 1

Answer:

a^2 + b ^2 + 2ab, a^2 + b^2 - 2ab

Step-by-step explanation:

Answer 2

Answer:

(a+b)^2 = a^2 + b^2 + 2ab

(a-b) ^2 = a^2 + b^2 - 2ab

Step-by-step explanation:

Expand them, take common and hence you'll get the derivation.
