(4a^3+6a^2b^3+3a^3b^3)/(1/5y)=?
(4a^3+6a^2b^3+3a^3b^3)/(1/5y)=?
(4a^3+6a^2b^3+3a^3b^3)/(1/5y)=?
(1/5y)?
题目错了吧?
A-B A+B 2B+A 3A-B 6A+2B
2(a+b)-[4(a+b)-3(a+b)]一[5(a-b)+(a-b)]过程
5(a*a*b-3*a*a*b)-2*(a*a*b-7*a*b*b)
(a+2b)(a-2b)+(a-b)(a+b)-2(a-3b)(a-b)
2a-{7b+[4a-7b-(2a-6a-4b)]-3a
(a+2b)(2a+4b)(3a+6b)(4a+8b)
(a-b)^6*[-4(b-a)^3]*(b-a)^2÷(a-b)=求过程
因式分解:3b(b-a)+6a(a-b)^2
2a(a-b)+4a(2a+3b)
(a^2+1)(-4a^2+1)+a^4-1 3a(a-b)(a+b)-6(b-a)^2a^2-9(a-b)^2= 3a(a-b)(a+b)-6(b-a)^2=
因式分解:1、a*a*a*a+2a*a*a*b+3a*a*b*b+2a*b*b*b+b2、(a+1)(a+3)(a+4)(a+6)-280
若a-b=4,3a+2b=6,3a(a-b)+2b(a-b)=( ).
(2/3a)-[2/(a+b)]{[(a+b)/3a]-a-b}÷[(a-b)/b]
(2/3a)-[2/(a+b)]{[(a+b)/3a]-a-b}÷[(a-b)/a]
化简:[2/3a - 2/(a+b) * (a+b/3a - a - b)] / (a-b)/a
计算:(4a-b)^2-[8a*(a-b)-(3a-b)*(3a+b)]
(3a-6b)/(a+b) - (5a-6b)/(a-b) - (4a-5b)/(a+b) - (7a-8b)/(a-b) 快
(3a-6b/a+b)-(5a-6b/a-b)-(4a-5b/a+b)-(7a-8b/b-a)
