Verify the identity (a-b)- a -2ab + b' geometrically by taking(i) a=3 – InterviewSolution

1.

Verify the identity (a-b)- a -2ab + b' geometrically by taking(i) a=3 units, b=1 unit

Answer»

LHS : (a-b) ^2= (a-b)(a-b)= (3-1)(3-1)= 2x2 = 4

RHS : a^2 - 2ab + b^2= 9 - 2x3x1 + 1= 9 - 6 +1= 3+1 = 4

Hence Proved
