You can put this solution on YOUR website!
2q^2+14q = 2q-q^2-9
\n" ); document.write( "First we should put all the numbers on one side
\n" ); document.write( "2q^2+q^2-2q+14q+9 = 0
\n" ); document.write( "3q^2+12q+9 = 0
\n" ); document.write( "Now we can use the quadratic formula
\n" ); document.write( " $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29\"$
\n" ); document.write( " $\"x+=+%28-12%2B-sqrt%2812%5E2-4%283%29%289%29%29%29%2F%282%283%29%29\"$
\n" ); document.write( " $\"x+=+%28-12%2B-sqrt%2836%29%29%2F6\"$
\n" ); document.write( " $\"x+=+%28-12%2B-6%29%2F6\"$
\n" ); document.write( "x = -6/6 or -18/6
\n" ); document.write( "x = -1 or -3 \n" ); document.write( "

\n" );
