Use the one-to-one property of logarithms to solve

Question. . log9 (2n2 − 14n)= log9 (−45 + n2 )


=2n2-14n = -45 + n2

=2n2-n2-14n+45=0

=n2-14n+45=0

=(n-5)(n-9) = 0

=n-5=0 or n-9=0

=n-5=0 or n-9=0

=n = 5 or n= 9


Is this correct up to here?


and then, what is the final answer and how to solve this question?

I don't know the next step.
