Question

помогите пожалуйста!!!!!!​

Answer 1

Ответ:

$\frac{2p - p}{ {p}^{2} + qp } - \frac{2q - p}{pq \times {q}^{2} } = \frac{2p - q - 2q - p}{ {p + qp + {q}^{2} }^{} } = \frac{1}{ {p}^{2} + {q}^{3} }$

Answer 2

2p-a/p2+qp - 2p-a/pq+q2 = (2p-q)*q/p*(p+ q) - (2q-p)*p/q*(p+q) = 2pq-q2-2pq+p2/pq(p+q) = p2-q2/pq*(p+q) = (p-q)*(p+q)/pq*(p+q) = p-q/pq
