You can put this solution on YOUR website!
if you are finding the solution of x ,
\n" ); document.write( "use cross multiply
\n" ); document.write( "so ,
\n" ); document.write( "(2x - 1)(3x + 4) = (x + 4)(x + 3)
\n" ); document.write( "6x^2 + 8x - 3x - 4 = x^2 + 3x + 4x + 12
\n" ); document.write( "6x^2 - x^2 + 5x - 7x - 4 - 12 = 0
\n" ); document.write( "5x^2 - 2x - 16 = 0\r
\n" ); document.write( "\n" ); document.write( "use $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( "so it will be
\n" ); document.write( "

\n" ); document.write( " $\"x+=+%28+2+%2B-+sqrt%28+324+%29%29%2F%28+10+%29+\"$
\n" ); document.write( "2 +- 18 / 10
\n" ); document.write( "x = (2+18)/10 or (2-18)/10
\n" ); document.write( "x = 2 or -1.6 \n" ); document.write( "

\n" );
