You can put this solution on YOUR website!
I'm assuming what you're asking is :
\n" ); document.write( ":
\n" ); document.write( "(x/3) = 4 / (x+1)
\n" ); document.write( ":
\n" ); document.write( "(x^2) + x = 12
\n" ); document.write( ":
\n" ); document.write( "(x^2) + x - 12 = 0
\n" ); document.write( ":
\n" ); document.write( "By factorisation:
\n" ); document.write( ":
\n" ); document.write( "(x + 4)(x - 3) = 0
\n" ); document.write( ":
\n" ); document.write( "Therefore, x = -4 or x = 3 \n" ); document.write( "

\n" );
