Respuesta :
You can substitute numbers in for x to prove it is not true:
4x+5x² and 9x³
Using 3 for x,
4(3)+5(3²) and 9(3³)
12+5(9) and 9(27)
12+45 and 243
57 and 243
These are obviously not the same.
Algebraically speaking, they do not go together because x³ is multiplying; we did not multiply x² and x, we added them.
