You can put this solution on YOUR website!
log (x-1) + log (5) = log (x^2-1)
2 2 2

This is how to write it properly:
log(2,(x-1))+log(2,5)=log(2,(x^2-1))

log%282%2C%28x-1%29%29%2Blog%282%2C5%29=log%282%2C%28x%5E2-1%29%29

log%282%2C%28x-1%29%285%29%29=log%282%2C%28x%5E2-1%29%29

5%28x-1%29=x%5E2-1

x%5E2-1-5x%2B5=0

x%5E2-5x%2B4=0, and you can handle the rest...
