Equation
billy was doing maths. He proceeded as follows, Let, a=b Multiplying both the sides with a, he got, a2=ab Subtracting b2, from both the sides, he got, a2- b2= ab- b2 Now, a2- b2 = (a+b)(a-b) So, (a+b)(a-b)= ab- b2 Taking b as common, (a+b)(a-b)=b(a-b) Now, cancelling the common term (a-b), he got, (...
