if , then the correct substitution would be ...
try again ...
Can anyone help me with this?
then flip them and rearrange so I get
then mutiply all by two to get rid of fraction.
then I factor and end up with
I think the problems begin when I sub back in the ... doing something wrong and not getting book's solutions.
btw those -1's are supposed to be superscripted, not sure why its not working :/
OK, so I have wrapped my head around that early error I made.
I'm getting tripped up after the factorization still though, and the book unfortunately has example subbing with negative exponents with single variable but none with a constant and a variable plus negative exponent.
So after I sub back in. I will only list one of the zeros since I think once I see what I am missing the second shouldn't be hard.
my factorization is now
which after subbing back in the first one yields me
from there I tried finding a common denominator
and adding them like so
But not sure if that was correct, or what to do next. Can someone give me a clue please?
