Question

Simplify : (a + b)sqare 2 - (a-b)sqare 2​

Answer 1

Answer:

4ab

Step-by-step explanation:

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

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

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

putting value of (a + b)^2 & (a - b)^2 in above equation.

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

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

2ab + 2ab

4ab
