What happnes if the co-efficient of x^2 is a differnt number such as 3. Woudl you still use x when putting into and equation?

[mathstutorbiz]

@FoziaYaqoob This particular operation "completing the square" can ONLY be performed with x^2.

I have double checked. The mistake is yours. mathstutor.

@havapintoflager I know this is a little late but could be beneficial for anyone watching now that got the same answer, what I think you did was recognised that root 12 = root 4 x root 3 but forgot to change root 4 into 2

this is nice and clear, i was a little shakey on completing the square but i think i'll do fine now. at least i don't have the worry of time on my mind (i get 100% extra if i want it) so i can concentrate on the questions and not on the clock

is there a video on the trapezium rule?

I think it would really help me if you could do one and if you have, which on is it? Thanks

[mathstutorbiz]

If you visit mathstutorDOTbiz and check the contents of all the available videos you will find this topic on one of them..... but not necessarily a freebie on youtube. Only a selection of vids are one youtube mathstutor
