__Expand__'/'

__distribute__' and '

__factor__'

I've never studied math in the English language. And now I'm taking a calculus class, and I have a little problem with some basic terms.

Do 'Expand' and 'Distribute' mean the same ?

lets say : 2x(2x+5)=> expanding : 4x^2 +10x.

Is What I just did called

**expansion**/

**distribution**?

And If I have 4x^2+10x and I '

**factor**'/'

**factorize'**/'

**take out common factors',**I get => 2x(2x+5).

??

I think I need only these terms straightenedout, all the others seem to be similar in Hebrew.

Thanks.
