You have helped me so much tomorrow is my last day of year 11 and i have a maths paper 3 at 9:30 and all i can say is thank you i dont know where id be without you rn
Because if you factorise 3x* -16x -12 you get to (3x+2)(x-6), the (x-6) on the numerator and denominator cancel out consequently leaving you with x-2 over 3x+2, Answering your question of “why is it over 3? “
Personally, I prefer to use the "AC method". It's fairly straightforward and even if you make a mistake with the signs, you should be able to spot it right away. ( Since it's just that; a*c, and a+c for the middle term). And then I carry on and "split the middle term" according to my ac "diagram"and then factor it into two brackets. Overkill? Maybe, but it leads me to the correct answer and it's unlikely that I would make any mistake on this part of the question. As long as the problem at hand is factorable, this works. You gotta write slightly more though, while working out the problem. But that's the tradeoff.😅

Did you do well?
@@Draggie306 how did it go?
How was it
was it good?
6 hours later and I finally get it... thank you!
You have the Best explanation of this topic on UA-cam!!
My guy just saved my maths test tmmrw morning
thank u :)
x^2 -8x +12
3x^2-16x-12
why is it over 3? I don't understand
exactly

It's x squared so it's not 3 squared. The square indices belong to x not 3. Later you will factorise getting two x in the brackets.
Literally
Thanks for you if you can speak Arpic explain with it
still struggling with the signs(-/+) when i factorise it;-; got any tips?
Yeah im also still struggling there
Same
I know it's probably late now but practice solving quadratic equations to get good at it

9:51 why do you need to make 2 into a fraction?
wick doesn’t know math😢
i confusning
saem
can you sign my autograph mr hegarty
Early :D
