Question

I'm puzzled by this operation: a^2 - 2ab + b^2 / a - b; a * a - 2ab + b * b and I get a - 2ab + b which doesn't seem to be right.

Can you explain what I may be doing wrong? Thanks!

Answer 1

\[\left( a-b \right)^{2}\div(a-b)\]

Answer 2

(a-b)(a-b)/(a-b)
=a-b

Answer 3

is it clear

Answer 4

Oh, now I understand what I was doing wrong! Thanks! :-)

Answer 5

ok

Answer 6

The result is indeed a - b :) which is what I get now, thanks to you! :)
