That's wrong it should be B- C?

I don't see anything wrong with the tutor's workings and he did not copy the question wrongly.

I have confirmed this using the Symbolab software

What do you mean by "B - C'? Which line?

I mean if you multiply the x by the y square then add in B- put it into C B- -C

There is no y here. You might have looked at a different question rather than this one.
