To simplify 75/54, we first need to find the greatest common factor. Our GCF is 3, so we will divide both number by 3. 75/3=25, and 54/3=18.
75/54 simplifies into 25/18 or 1 7/18
Basically, take the union of both domains
g(x)=x/(1-x)
1-x=0
1=x
x=1 is restricted because it makes you divide by 0
f(x)=(1-x)/(1+x)
1+x=0
x=-1
x=-1 is restricted because it makes you divide by 0
domain is all real numbers except -1 and 1
If there are fractions, eliminate them using the right methods. Then gather x and y terms on one side, and the rest on the other side. Simplify.
