Of course. I was just completing his intermediate step.Correct, you can continue simplifying though!Correct me if I'm wrong..but..that's not correct.a(b−a)=(b+a)(b−a)
Simplify and add 1 to both sides:
a=b+a
The simplest form looks like ab=b^2
EDIT: Arjun got to it before me...
ab=b^2
b(b) = b^2 (by hypothesis since a = b)
b^2 = b^2
1 = 1 (by dividing both sides by b^2)
