I have a homework sheet that I need help on.
I am stuck on a list of problems and I've done a lot of research to try and solve them with no luck.
I have to reduce them and state the restrictions.
1st problem:
m^2-4m+4
 m^2-4

I have reduced it to (m-2)(m-2) so far but I don't even know if I did that correctly. Can you help?

I can also post pictures of the fractions if that helps.

You must find where numerator and denominator are zero.

1) ANYWHERE the denominator is zero, discard it from the Domain. This is a restriction.
2) If the numerator is zero at the same spot, it's still a restriction, but it can be corrected by an additional definition.
 
Yes, I missed quite a lot of my class.
After reducing it like that, how do I make it a fraction again?
 
Ok, but I am still confused.
Isn't the denominator supposed to equal 0 or did I miss something?
 
You have to find the restriction. As mentioned above, a restriction is where the denominator is 0.
To find the points, where the denominator is 0, you have to set denominator = 0.
Each x for which the denominator is 0, the fraction is not defined and therefore, you have to discard them from the Domain.
