Heya.......!!!!

Your Question :-
 = > \: \: 2log_{4}(x) \: = \: 1 \: + \: log_{4}(x - 1) \\ = > log_{4}(x {}^{2} ) - \: log_{4}(x - 1) = 1 \\ \\ = > \: log_{4}( \frac{x {}^{2} }{x - 1} ) \: = 1 \\ = > 4 {}^{1} = \frac{x {}^{2} }{(x - 1)} \\ = > x {}^{2} = 4x - 4 \\ this \: becomes \: quadratic \: equation \: \\ = > x {}^{2} - 4x + 4 = 0 \\ = > (x - 2) {}^{2} = 0 \\ = > > \: \: x = 2
