Algebra.Com's Answer #595954 by addingup(3677)![]() ![]() You can put this solution on YOUR website! You have the correct solution.\r \n" ); document.write( "\n" ); document.write( "(log(x^2))/(log(3))-(log(x+6))/(log(3)) = 1. Now I multiply both sides by log(3) \n" ); document.write( "log(x^2)-log(x+6) = log(3)etcetera. You've already done the problem so it saves me some writing. \n" ); document.write( "You factor the left and get: \n" ); document.write( "(x-6) (x+3)= 0 \n" ); document.write( "x-6= 0 or x+3= 0 \n" ); document.write( "x= 6 or x= -3 This is your solution \n" ); document.write( " \n" ); document.write( " |
