You can put this solution on YOUR website!
start by making the equation equal to 0.
\n" ); document.write( " $\"75x%5E2=60x%2B12\"$
\n" ); document.write( " $\"75x%5E2-60x-12=0\"$
\n" ); document.write( "each of these coefficients can be divided by 3.
\n" ); document.write( " $\"3%2825x%5E2-20x-4%29=0\"$
\n" ); document.write( "you can't factor this number so you need to use the quadratic equation. We will ignore the 3 for now
\n" ); document.write( " $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( " $\"x+=+%28-%28-20%29+%2B-+sqrt%28+%28-20%29%5E2-4%2A25%2A%28-4%29+%29%29%2F%282%2A25%29+\"$
\n" ); document.write( " $\"x+=+%2820+%2B-+20+sqrt%282%29%29%2F%2850%29+\"$
\n" ); document.write( "simplify
\n" ); document.write( " $\"x+=+%282+%2B-+2sqrt%282%29%29%2F%285%29\"$
\n" ); document.write( "now we will bring the 3 back from earlier
\n" ); document.write( " $\"x=3%28%282+%2B-+2sqrt%282%29%29%2F%285%29%29\"$
\n" ); document.write( " $\"x=%286+%2B-+6sqrt%282%29%29%2F%285%29\"$ \n" ); document.write( "

\n" );
