Question

What is (a+b)²?
Give an example.​

Answer 1

Answer:

Instead of multiplying 105 x 105 to get the value of (105)² we can use algebraic formula for a plus b whole square that is (a+b)² to get the same answer. 105 can be written as 100 + 5. (105)² = (100 + 5)² (a + b)² = a² + b² + 2 a b. a = 100 b = 5.

Answer 2

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