It's a matter of semantics.
\n" ); document.write( "quadratic is 2nd order, or exponent 2. It comes from quadrangle, which is rectangular.
\n" ); document.write( "---------------
\n" ); document.write( "But, as the other tutor pointed out, it can be a quadratic in x^4, which gives and exponent of 8.
\n" ); document.write( "If the exponents are in order as in his example, 8, 4, 0, then it's a quadratic in x^4. It's \"a%28x%5E4%29%5E2+%2B+b%28x%5E4%29%5E1+%2B+c%28x%5E4%29%5E0+=+0\"
\n" ); document.write( "-------------
