Hello,

I have two questions! I dont' want to be spoon fed the answers :-) just need some direction on websites, and, the categories of maths that these questions relate to if Im not using the right terms.

1. Is it possible to simplify this equation; z = ((x/2)+0.5)*x ?

If it is are there any web pages you could direct me to so I can teach myself

what I need to know to simplify it?

2. Are there any web pages that can show me what I need to know to re-arrange this equation so I get x from z?

It's been a while since I have done much with maths, so please be patient with me :-)

Many thanks in advance.
