Algebra.Com's Answer #456587 by Alan3354(69443) You can put this solution on YOUR website! log(x^2 + 4) - log(x+2) = 3 + log(x - 2) \n" ); document.write( "log(x^2 + 4) - log(x+2) = log(1000) + log(x - 2) \n" ); document.write( "---- \n" ); document.write( "(x^2+4)/(x+2) = 1000(x-2) \n" ); document.write( "x^2+4 = 1000(x^2-4) = 1000x^2 - 4000 \n" ); document.write( "999x^2 = 4004 \n" ); document.write( " \n" ); document.write( "x =~ 2.002 \n" ); document.write( "---------------- \n" ); document.write( "Ignore the negative value of x \n" ); document.write( " |
