Example: 4x 3 x + 2 The Degree is 3 (the largest exponent of x) For more complicated cases, read Degree (of an Expression). Good question! If we assume that the polynomial has a degree of 2: Then we know that the roots of such a quadric equation are given by: This shows that the two roots $\lambda_1$ and $\lambda_2$ are conjugates of each other. The reason is that all of the exponents are whole numbers for the variable x (2 in the first term, 1 in the second term, and 0 in the third term). A polynomial cannot have a radical, since this would mean that there are powers of a variable that are not whole numbers.
