2^2x1  3 times 2^x1 + 1 = 0

if either term is 0, the whole thing is zero, so this is two problems:
a) 2^(2x1)  3 = 0
or
b) 2^(x1) + 1 = 0
NOTE  You did not give me parentheses, so I am guessing what you mean.
problem a
2^(2x1) = 3
(2x1) log 2 = log 3
(2x1) = .477/.301 = 1.58
2x = 2.58
x = 1.29
or
problem b
2^(x1) = 1
there is no such thing as log 1. I am stuck, no solution
the question is: Two to what power = 1
There is no such power.
therefore the only solution is problem a
