Respuesta :

To answer the question, simplify the polynomial by adding those that has the same degree of variable,
                                   6 - 3x + (6x³ - 2x³)
                                   6 - 3x + 4x³
Rearrange the polynomial with decreasing exponent or x,
                                     4x³ - 3x + 6
This is a third-degree polynomial.
