Wow! What an amazing video. This has managed to get in my head: FACTORISE WHEN REARRANING WITH 2 SUBJECTS! Really clear and concise, gonna help me out a lot with my mock in a couple weeks! (I also used your website for revision for biology, and physics so far, and in those tests I think I did well! Certainly gonna use the website for my chemistry mock soon. :D)

On the first question, when expanding the 2nd brackets, why does x come before y?
@ice_wallow_come9741
@ice_wallow_come9741 3 года назад
*It generally doesn’t matter, but it’s better if you arrange the letters alphabetically. Because the letter x comes before y in the alphabet, we put the x before the y.*

My only problem is that my teacher taught me another method and I don't like it and most people use this method but all the questions that my teacher gives me has little or no numbers to divide subtract or multiply so I can't really implement this method from part 1 or 2

Hi mate, on the 2nd question, why do we x by b-5 rather than 2-7b?
@changran5519
@changran5519 5 месяцев назад
because you are trying get the subject letter on its own instead of the non-subject terms
@user-np3co3jj1p

@ryze5436
@ryze5436 3 года назад
Move b to the other side that would give s over b then you take the square root because that is the opposite of squared so that would give the answer of square root of s over b 😁
