2x^2 /(divided by) x^2 + 1x - (minus) -2x^2 + 2x-1x-1 /(divided by) x^2 + 1x

okay question is,

does the minus distribute into the 2x^2 + 2x -1x -1 ?

hence equation becomes -2x^2 - 2x +1x +1

or,

does the minus only distribute into the the first part 2x^2?

hence equation becomes -2x^2 + 2x -1x -1

thanks
