oh yeahh.. Thanks mate!

Much easier to just take the outside the integral and integrate

Hey guys one more thing... What's the easiest way for you guys to find the number that adds and also equals to the number when multiplied for the fatorising questions. for example this, Factorise 2x(squared) – 7x + 3.

How would you guys find the no. in the brackets... whats the easiest way? I'm not really good at that shiettt. (#Mathsismyworstsubject)

Do the cross method and practice it heaps and you can immediately tell. For me I visualise the cross method and make a good guess of what numbers to put in the brackets.

Seems like you're going to have to do quadratics the hard way

This video described a pretty snazzy method to factorize. http://www.youtube.com/watch?v=FxTiogyhwfc

Learnt that from your mother. She kept wanting me to dip my ball"sacks" in her mouth... So it just got stuck in my head :/

It can solve quadratics lol

Yes true! I've just learnt that way for some reason.
