Question

(17p-12q)² ......ayudaaaaaa​

Answer 1

Usamos el (a - b )² = a² - 2ab + b² :

$(17p {)}^{2} - 2 \times 17p \times 12q + (12q {)}^{2}$

Elevamos cada factor a la potencia

$289 {p}^{2} - 2 \times 17p \times 12q + (12q {)}^{2}$

ahora calculamos

$289 {p}^{2} - 480pq + (12q {)}^{2}$

elevamos el factor a la potencia

$289 {p}^{2} - 408pq + 144 {q}^{2}$
