In order to write a polynomial in standard form, we need to arrange the terms by degree in descending numerical order. To do that, we first need to classify the highest exponent of the variable.
2x - 3x^2 +6 + 5x^3
The highest exponent of the polynomial, and therefore its degree, is 3. We can now arrange the terms according to their exponents.
2x - 3x^2 +6 + 5x^3
⇕
5x^3-3x^2+2x+6
