I've got an A level exam in a month and I need help.

The curriculum sheet for my course says I need to know the following:

"recognise and solve equations in x which are quadratic in some form of x, eg. x^4 - 5x^2 + 4 = 0."

I'm working from memory as I can't find a book that covers the subject. I seem to remember having to substitute in: " z = x^2 ".

I can do that and then solve for z (as with a normal quadratic) and I get : z = 4, z = 1.

It's here where i get stuck.

Do I now let z = 4, therefore x = (plus or minus)sqrt 4 and
let z = 1, therefore x = (plus or minus)sqrt 1

This gives me 4 answers, which must be wrong!

Help!

I have always had trouble with integrals, and I would LOVE to be able to throw a ton at some type of solver such as the one calc101.com has that show me HOW they do the solving so I can learn.

I know matlab and maple both are programs that solve math problems, and I own both. The problem is they don't show step by step solving. Or at least I don't know how to do so in them.

lim as x goes to 4 of (4 - x) / (square root of x - 2)

lim as x goes to zero of (x - tan x) / (x - sin x)

lim as x goes to zero of (1 - cos^2 (2x) ) / x^2

if you could explain any of these it would be so great!!! thank you so much in advance.
