Hey, I've started a new school and won't be posting here anymore. Thanks for all the help.

This is the next one;

It's just x^2 I think.

Opps I meant "- 3"

Should it be? Should there be a dot between them?

Haha, I didn't think you would be able to read that!

Is this better?

And I'm there.

I don't know how to use codecogs..

Okay, awesome. I got 7 wrong in my current lesson, so 5 more to go!

This one was number 13 in my lesson.

13.

Do I use the same method as the last one?

Awesome, thank you!

I have 5 more problems similar to this. Can I post them here and we can work through them?

becomes

That second "dot" wasn't meant to be there, my bad.

So,

I don't know how to insert that dot you have in your posts so I just slept out "dot" instead

I really don't know how to do this as you can see.

So,

Except the "3" should be the first number in the equation.
