You can put this solution on YOUR website!
1) From 3x^2=2a, we divide by 3 and get
\n" ); document.write( "x^2 = (2/3)a
\n" ); document.write( "then take the square root and get
\n" ); document.write( "x = $\"%2B-sqrt%282a%2F3%29\"$
\n" ); document.write( "which can be simplified by rationalizing...
\n" ); document.write( "2) For x^2 - 3x - 15 = 0, we will have to use the quadratic formula, since it isn't factorable...we get
\n" ); document.write( " $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( " $\"x+=+%283+%2B-+sqrt%289+-+4%2A1%2A%28-15%29%29%29%2F2+\"$
\n" ); document.write( " $\"x+=+%283+%2B-+sqrt%2869%29%29%2F2\"$ \n" ); document.write( "

\n" );
