Hi,\r
\n" ); document.write( "\n" ); document.write( "This is polynomial. Put simply, a polynomial is when you take different (non-negative integer) powers of x, and add lots of them together. One way of grouping polynomials is by their highest power of x. In your example \"2x%5E3%2B6x-1\" the highest power of x is 3, and this is called a cubic polynomial.\r
\n" ); document.write( "\n" ); document.write( "A quadratic is a polynomial where the highest power of x is 2. So for a polynomial to be quadratic the highest power of x must be exactly 2.\r
