(6a^2b-9a^3)/(-3a)^2 计算
(6a^2b-9a^3)/(-3a)^2 计算
原式
=(6a²b-9a³)/(9a²)
=6a²b/(9a²)-9a³/(9a²)
=2b/3-a
(6a^2b-9a^3)/(-3a)^2
=(6a²b-9a³﹚÷﹙9a²﹚
=2/3b-a
(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=
A-B A+B 2B+A 3A-B 6A+2B
5(a*a*b-3*a*a*b)-2*(a*a*b-7*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
(a+2b)(a-2b)+(a-b)(a+b)-2(a-3b)(a-b)
9(a-b)(a+b)-3(a-b)^2
因式分解:3b(b-a)+6a(a-b)^2
(2/3a)-[2/(a+b)]{[(a+b)/3a]-a-b}÷[(a-b)/b]
3a^2b-{2a^2b+[9a^b-(6a^2b+4a^2)]-(3a^2b-8a^2)}=
对任意自然数a,b,规定a#b=2*a+b,若a#2a#3a#4a#5a#6a#7a#8a#9a=3039,则A=()
先化简,再求值:(2a-b)^2-(2a+b)(a-b)-3(a-3b)(a+3b),其中|a-1|+b^2=6b-9
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
2a-{7b+[4a-7b-(2a-6a-4b)]-3a
a^2b-a^3-9b+9a因式分解,
a+2b/2a-3b=3 求解4b+2a/9b-6a-4a-6b/3a+6b=?
当a+2b/2a-3b=3,求代数式4b+2a/9b-6a-4a-6b/3a+6b
a+2b/2a-3b=3 求解4b+2a/9b-6a-4a-6b/3a+6b=?
