9u³-2u -7

es suma de esos dos términos algebraicos ayuden pliss
​

Answer 1

Respuesta:

$3 {u}^{3} - 5 {u}^{2} - u + 3 \\ 3 {u}^{3} - 3 {u}^{2} - 2 {u}^{2} + 2u - 3u + 3 \\ 3 {u}^{3} \times (u - 1) - 2u \times (u - 1) - 3(u - 1) \\ (u - 1)(3 {u}^{2} - 2u - 3)$

$9 {u}^{3} - 2u - 7 \\ 9 {u}^{3} - 9 {u}^{2} + 9 {u}^{2} - 9u + 7u - 7 \\ 9 {u}^{2} (u - 1) + 9u(u - 1) + 7(u - 1) \\ (u - 1)(9 {u}^{2} + 9u + 7)$
