@jamesjames304 11 дней назад

It's been 4 years, but to answer your question, he did not use the sum of two cubes-rather he used the sum of two squares of (x²-4) which is equal to (x+2)(x-2). Additionally, the 4/6 is equal to 2/3.

Why can't we cancel (x+3) and (x+3) at 2:20?

@michy_documents 4 года назад

You cannot cancel across, only diagonal and/or vertical. Since the two (x+3) are both in the numerator, you can write them as one and simply square it. It's just the same as (x+3)(x+3). I hope this helps.
