We want to simplify:
first we factorize
as
then multiply
by
to equalize the denominators of the first expression, and add the fractions.
simplify x+3:
a.
b.
steps already described
c.
x cannot be -1, nor -3 because the fractions with denominators (x+1) and (x+3) would not be defined.
(x-5)^2+(y+4)^2=100
hope this helps
