整式的计算(p-8q)(8q+p)-(p+8q)(8q-p)整式的计算(p-8q)(8q+p)-(p+8q)(8q-p)整式的计算(p-8q)(8q+p)-(p+8q)(8q-p)=(8q+p)(2p

整式的计算(p-8q)(8q+p)-(p+8q)(8q-p)
整式的计算(p-8q)(8q+p)-(p+8q)(8q-p)

整式的计算(p-8q)(8q+p)-(p+8q)(8q-p)
=(8q+p)(2p-16q)
=2(8q+p)(p-8q)
=2p*p-128q*q

=(p-8q)(p+8q)+(p+8q)(p-8q)
=2(p+8q)(p-8q)
=2(p²-64q²)
=2p²-128q²

(p-8q)(8q+p)-(p+8q)(8q-p)
=8pq+p²-64q²-8pq-8pq+p²-64q²+8pq
=2p²-128q²
