log10(x) + log10(x – 3) = 1
\n" ); document.write( "----------------
\n" ); document.write( "log10[x(x-3)] = 1
\n" ); document.write( "----
\n" ); document.write( "x(x-3) = 10^1
\n" ); document.write( "---
\n" ); document.write( "x^2-3x-10 = 0
\n" ); document.write( "-----
\n" ); document.write( "(x-5)(x+2) = 0
\n" ); document.write( "---
\n" ); document.write( "Positive solution:
\n" ); document.write( "x = 5
