You can put this solution on YOUR website!
Use the quadratic formula where:
\n" ); document.write( "a=1
\n" ); document.write( "b=18
\n" ); document.write( "c=63
\n" ); document.write( ".\r
\n" ); document.write( "\n" ); document.write( "\"x+=+%28-18+%2B-+sqrt%28+18%5E2-4%2A1%2A63+%29%29%2F%282%2A1%29+\"[Plug-in the values and solve]
\n" ); document.write( "\"x+=+%28-18+%2B-+sqrt%28+324-252+%29%29%2F%282%29+\" [Combine terms and simplify]
\n" ); document.write( "\"x+=+%28-18+%2B-+sqrt%28+72+%29%29%2F%282%29+\"[Factoring 72 = 2*4*9]
\n" ); document.write( "\"x+=+%28-18+%2B-+6sqrt%282%29%29+%2F%282%29+\"
\n" ); document.write( "\"x+=+2%28-9+%2B-+3sqrt%282%29%29%2F%28+2%29+\" [Factor out \"2\"]
\n" ); document.write( "\"x+=+%28-9+%2B-+3sqrt%282%29%29%29\" [Cancel out \"2\"]
\n" ); document.write( "\"x+=+%28-9+%2B-+3sqrt%282%29%29\"
\n" ); document.write( "x=-13.2426 or x = -4.7573
\n" ); document.write( "
\n" ); document.write( "
