[drifting jay]

why is it turned into -4x?

[meager bough]

they factored out -1 from (1-2x)

so it becomes (-1+2x)

either way this is how i would do it

1-2x/2x-1 will cancel out and give u -1, it's basically like 6/-6 which gives -1 if that helps

Ahah am still so confused

[meager bough]

which bit

[drifting jay]

-1 + 2 n 1-2 is the same thing no?

[meager bough]

They are

So they can be cancelle down
