问题描述：
Simplify the expression:
1.(6ax-2a)/(b(ab+b^2)) × (b^2 〖(a+b)〗^2)/(3ax-a)
2.(a^2 b+ab^2)/(3x^2)+3xy) ÷ (ab+a^2)/(x^2 y)
3.(2〖p-q〗^2)/(3q^2) × ((p^2)q)/(pq-x^2) ÷ (2q-2p)/(-6)
3.(2〖p-q〗^2)/(3q^2) × ((p^2)q)/(pq-p^2) ÷ (2q-2p)/(-6)
对不起,写错了,没有x,是p
答
1.原式=(6ax-2a)/b×(a+b)/(3ax-a)=2(a+b)
2.原式=(a*b+b^2)/(3x+3y)×xy/(a+b)=bxy/(3x+3y)
3.貌似写错了,不应该有x
