Assuming base ten.

2log%2810%2C1-x%29=log%2810%2C%28x%2B5%29%28x%2B5%29%29
log%2810%2C%281-x%29%5E2%29=log%2810%2Cx%5E2%2B10x%2B25%29
Logs to the same base, so arguments equal.
%281-x%29%5E2=x%5E2%2B10x%2B25
1-2x%2Bx%5E2=x%5E2%2B10x%2B25
1-2x=10x%2B25
1-25=12x
highlight%28x=-2%29

Which base was not needed to be known.
