z=x^2-yx
\n" ); document.write( "subtract z from each side
\n" ); document.write( "x^2-yx-z=0 now use the quadratic formula
\n" ); document.write( "for equation in the form ax^2+bx+c=0
\n" ); document.write( " $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( "so we have
\n" ); document.write( " $\"x+=+%28y+%2B-+sqrt%28+%28-y%29%5E2-4%2A1%2A%28-z%29+%29%29%2F%282%2A1%29+\"$
\n" ); document.write( " $\"x+=+%28y+%2B-+sqrt%28+y%5E2%2B4z+%29%29%2F%282%29+\"$ \n" ); document.write( "
