Are there any questions in particular you'd like to discuss? Surely you can't be stuck on all of them!

Well how about maybe 2, 3 and 7?:)

Sure. :)
Question 2: We've got a function of , . We want , so write in place of in the expression:
using .
(I need to pop out, to anyone else for the others?)

wow thanks, its a lot less scary looking now! your the best! :D

For # 3 whenever you have an expression in the form.. ..you can multiply diagonally and the following is true..
So we have:..
Cross multiply:..
Solve for . You should get 2 for .
Now for # 7 are you familiar with the factoring method for quadratics?
Whenver you have an expression in the form.. .. you look for 2 numbers that multiply to get you and add up to .
So our quadratic is:..
Since a is 1, we always start with this:
But since c is negative, we now have:
We know
Also
Plus
We need the two multiples to add up to 1. These are and .
So the factored form is:..
