Best ResponseYou've already chosen the best response.0Bring over the righthand side and take out the common factor of 9^x. You have\[9^x(x^22x3)=0\]

Best ResponseYou've already chosen the best response.0There is no x here that will make 9^x zero (if you plot any exponential function, you'll see that it never crosses below the xaxis)

Best ResponseYou've already chosen the best response.0But,\[x^22x3=(x+1)(x3)\]so your second factor has that\[(x+1)(x3)=0 \rightarrow x=1,3\]
