log%28x%5E2+-+2x+%2B+1%29+%3E+log%2825%29
log%28%28x-1%29+%5E2+%29+%3E+log%285%5E2%29
2log%28x-1%29+%3E+2log%285%29
log%28x-1%29+%3E+log%285%29
The log is an increasing function, so if log+%28x-1%29+%3E+log%285%29 then x-1
should be greater than 5.
So x-1+%3E+5, which means x+%3E+6.
your answer is: (d) x+%3E+6
