(2a^2-2/3a-4/9)(-9a)
(2a^2-2/3a-4/9)(-9a)
=2(9a²-3a-2)(-a)
=(-2a)(3a+1)(3a-2)
(2a^2-2/3a-4/9)(-9a)
=-a (18a^2-6a-4)
=-a*(6a+2)(3a-2)
=-2a(3a+1)(3a-2)
原式=-18a^3+6a^2+4a
=-2a(9a^2-3a-2)
=-2a(3a-2)(3a+1)
a-2a+3a-4a+5a-6a+7a-8a+9a-10a+11a.+99a-100a=
求和:1,a+a^2,a^3+a^4+a^5,a^6+a^7+a^8+a^9,···(a不等于0)

1.3a(2a的平方-9a+3)-4a(2a-1)
计算:a²+9-6a分支2a²-4a-6/(4a+8)×4+3a-a²分支6+a-a²
计算:a²+9-6a分支2a²-4a-6/(4a+8)×4+3a-a²分支6+a-a²
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=()
因式分解 9a(a-4)-6a(4-a)-3a(4-a)^2=
a-2a-3a+4a+5a-6a-7a+8a+9a-10a-11a.+2008a+2009a-2010a-2011a如何合并同类项?
[(a^2-9)/(a^2-6a+9)+(3-a)/(a+3)]×(a-3)/a
5a-【a+(5a-2a)-2(a-3a)-4a】
分式的乘除:16-a平方/a平方+8a+16÷a-4/2a+8乘a-2/a+281-a平方/a平方+6a+9÷a-9/2a+6乘a+3/a+9
(4-2a)(a^2-6a+9)÷(3a-a^2)(a^2+2a-15)今天就要
3a-[(a^2+4a+4)/(a+2)]+[(a^2+6a+9)/(a+3)] 化简 快加
a²-6a+9分之a²+2a/a²-3a分之a²-4
已知a^2-3a+1=0,求a+1/a,a^2+1/a^2,a^2-1/a^2,a^3+1/a^3,4a^2-9a-2+9/(1+a^2)
(a^2-9)/(a^2+6a+9)除以(a-3)/(a^2+3a)减去(a-a^2)/(a^2-1)结果是多少?
(a^2-9)/(a^2+6a+9)除以(a-3)/(a^2+3a)减去(a-a^2)/(a^2-1)结果是多少?
