You can put this solution on YOUR website!
So;ve for x:
\n" ); document.write( "\"2log%28%28x%2B2%29%29+=+log%28%283%29%29%2Blog%28%282x%2B1%29%29\" Apply the \"product rule\" to the right side. \"Log%5Bb%5D%28M%29%2BLog%5Bb%5D%28N%29+=+Log%5Bb%5D%28MN%29\"
\n" ); document.write( "\"2log%28%28x%2B2%29%29+=+log%28%283%282x%2B1%29%29%29\" Apply the \"power rule\" to the left side.\"pLog%5Bb%5D%28M%29+=+Log%5Bb%5D%28M%29%5Ep\"
\n" ); document.write( "\"log%28%28x%2B2%29%29%5E2+=+log%28%283%282x%2B1%29%29%29\" therefore:
\n" ); document.write( "\"%28x%2B2%29%5E2+=+3%282x%2B1%29\" Simplify.
\n" ); document.write( "\"x%5E2%2B4x%2B4+=+6x%2B3\" Subtract (6x+3) from both sides.
\n" ); document.write( "\"x%5E2-2x%2B1+=+0\" Factor.
\n" ); document.write( "\"%28x-1%29%28x-1%29+=+0\", so the solution is a double root:
\n" ); document.write( "\"x+=+1\"
\n" ); document.write( "Check:
\n" ); document.write( "\"2log%28%28x%2B2%29%29+=+log%28%283%29%29%2Blog%28%282x%2B1%29%29\" Substitute x = 1.
\n" ); document.write( "\"2log%28%281%2B2%29%29+=+log%28%283%29%29%2Blog%28%282%281%29%2B1%29%29\" Simplify.
\n" ); document.write( "\"2log%28%283%29%29+=+log%28%283%29%29%2Blog%28%283%29%29\"
\n" ); document.write( "\"2log%28%283%29%29+=+2log%28%283%29%29\"
\n" ); document.write( "
\n" );
