log%289%2C%28x+%2B+4%29%29+=+log%289%2Cx%29+%2B+log%289%2C%28x%2B1%29%29
since log a + log b = log ab
log%289%2C%28x+%2B+4%29%29+=+log%289%2C%28x%29%2A%28x%2B1%29%29
If the logs of the two expressions are equal, the
expressions are equal
x+%2B+4+=+%28x%29%2A%28x+%2B+1%29
x+%2B+4+=+x%5E2+%2B+x
x%5E2+=+4
x = +2, -2 answer
