\n" ); document.write( "by DEFINITION, quadratic equation is an equation of the form:\r
\n" ); document.write( "\n" ); document.write( "\"ax%5E2%2Bbx%2Bc=0\" where \"a\", \"b\" and \"c\" be real numbers, with \"a%3C%3E0\"\r
\n" ); document.write( "\n" ); document.write( " So, to check if an equation is a quadratic equation,you want to make two passes through it (both sides):\r
\n" ); document.write( "\n" ); document.write( "-Does it have an \"x%5E2\" term appearing somewhere? If not, then it's \"not\" a quadratic equation.
\n" ); document.write( "Note: it can have lots of \"x%5E2\" terms! The only other two term types that are allowed are \"x\" terms and constants terms.\r
\n" ); document.write( "\n" ); document.write( "(For example: no \"x%5E3\" terms, \"no\" variables \"inside\" square roots, \"no\" variables in \"denominators\", and so on.)\r
\n" ); document.write( "\n" ); document.write( "So, sweep across the equation and look for \"anything\"\"+other\" than \"x\" terms and \"constant\" terms.\r
\n" ); document.write( "\n" ); document.write( "If you find any, then it's \"not\" a quadratic equation. \r
