3m(a-2b)-a+2b 2a(a+b)-4a 4a(x-y)-(x-y)
3m(a-2b)-a+2b 2a(a+b)-4a 4a(x-y)-(x-y)
3m(a-2b)-a+2b 2a(a+b)-4a 4a(x-y)-(x-y)
3m(a-2b)-a+2b
=3m(a-2b)-(a-2b)
=(3m-1)(a-2b)
2a(a+b)-4a
=2a(a+b-2)
4a(x-y)-(x-y)
=(4a-1)(x-y)

3m(a-2b)-a+2b
=3m(a-2b)-(a-2b)
=(a-2b)(3m-1)
2a(a+b)-4a
=2a[(a+b)-2)]
=2a(a+b-2)
4a(x-y)-(x-y)
=(x-y)(4a-1)
(a-b)^m+3(b-a)^2(a-b)^m
计算:(b-a)^5(a-b)^m+(a-b)^(m+3)(b-a)^2
计算:(a-b)^m+3(b-a)^2(a-b)^m(b-a)^5
(a+b)m^2-(b+a) 因式分解....................
m^2(a+b)-a-b因式分解
计算:(a-b)^(m)*(a-b)^(2)*[2(b-a)]^3*[(b-a)^(5)]^(2)/(a-b)^(m).
计算(a-b)^m(a-b)[2(b-a)]^3[(b-a)^5]^2÷(a-b)^m=
(a-b)^m*(a-b)*[2(b-a)^3*(b-a)^5]^2/(a-b)^m怎么做?
2m(a-b)-3n(b+a)因式分解
(a+2b)(a-2b)+(a-b)(a+b)-2(a-3b)(a-b)
5(a*a*b-3*a*a*b)-2*(a*a*b-7*a*b*b)
(a-b)^3m*(b-a)^2m÷(b-a)^5m
a(m-n)^2+(n-m)^3 (2)a(a+b)(a-b)-a(a+b)^2
-2a(a+b)+b(a+b)
已知a>b,则下列式子不一定成立的是( ) a :A-c>B-c B:2(B-a)>3(B-A) c:a(m)2>B(m)2 D;A/(m)2+1>b/(m)2+1
(2/3a)-[2/(a+b)]{[(a+b)/3a]-a-b}÷[(a-b)/b]
化简(2a-b/a+b-b/a-b)÷a-2a/a-b
(2a-3b)[(a+b)-b(a-3b)]
