Hi,
I have a real quick question. I suck at math and this popped up while finding a derivative. I am not sure if this should be in this part of the board or not, but I am putting it here cause this corresponds to the math level where this popped up.
If I have 3(2x+h)/h, would it be permissible to cancel out the h and leave 3*2x=6x, or is this incorrect?
This would be incorrect because if you expand it:
3(2x+h)/h
= (6x + 3h)/h
= 6x/h + 3h/h
= 6x/h +3
The h can only be canceled out if every term in the numerator had an h.
Hope this helps!
Ah, right, I see. I knew something was feeling wrong about it, but didnt know what. I'm not a good math person, but I know when I am prolly doing something wrong. Thank you.
Going back, I think I see where I might've went the wrong way.
I end up with
Can this be simplified toCause what I did was just take out the h from the

It would be better if you posted the whole question ..... Otherwise who knows whether you're even meant to haveas part of the working ....
