(32a^3b^2+8a^2b-2a^2b^2)÷4a^2b

化简：{[(2a-b)/(a+b)]-[b/(a-b)]}÷[(a-2b)/(a+b)] 计算：((a+b)(a-b)-(a-b)^2+2b(a-b))/4(a-b) 1.（a-b)^2（b-a)^3(a-b)^-4 (a+2b)(2a+4b)(3a+6b)(4a+8b) 计算a^2-b^2/a+b-4a(a-b)+b^2/2a-b a-b+2b²/a+b 化简(2a-b/a+b-b/a-b)除以a-2b/a +b 计算·[(2a+-b)/(a+b)-b/(a+b)]/(a-2b)/(a+b) 化简(2a-b/a+b-b/a-b)除以a-2b/a+b (a-b)(a+b)²-(a+b)(a-b)²+2b(a²+b²) A=B+B+B+B+B+B+B+B+B+B+B+B+B+B+B A-B×3=C C+2×7+2=1 [（a+2b)(a-2b)-(2a-b)²+(3a-b)(3a-5b)]÷2a
