6a^2b-9ab^2+3ab a^3-6a^2-7a (x^2+x)^2-(x+1)^2
6a^2b-9ab^2+3ab a^3-6a^2-7a (x^2+x)^2-(x+1)^2
6a^2b-9ab^2+3ab a^3-6a^2-7a (x^2+x)^2-(x+1)^2
6a^2b-9ab^3+3ab
=3ab(2a-3b^2+1)
a^3-6a^2-7a
=a(a^2-6a-7)
=a(a+1)(a-7)
(x^2+x)^2-(x+1)^2
=(x^2+x+x+1)(x^2+x-x-1)
=(x^2+2x+1)(x^2-1)
=(x+1)^2(x+1)(x-1)
=(x+1)^3(x-1)
3(-2ab+3a)-(2a-b)+6ab
化简:(-2ab+3a)-(2a-b)+6ab
(9a²-6ab+b²)/(3a²-ab),其中b/a=2
a^2-3ab+b^2/ab=( )/ab-3
a^2-3ab+b^2/ab=( )/ab -3
a^2b-ab+2ab^2-5a^b-4ab+3ab^2化简快
(a-b)^3+2ab(a-b)
[(a^2-b^2)/b]^2/(a^2+ab)^3*(ab/b-a)^2另:a^2+ab=9
计算3ab(2ab^2-ab-b^2)-6ab(a^2-2ab-b^2)
-2ab乘以(-a^+6a^b-3a+b)
分解因式3a^2b-6ab^2-ab
ab/a+b=3 a-2ab+b/2a-3ab+2b?
3a²-ab+6ab-2b²=?
(a^2b-ab-a+1)/(ab^2+3ab-b-3)÷(a^2+a_2)/(b^2+b-6)
a^2b^2-7ab+10.3a^3b-6a^2b-45ab.
3a²b-[2ab²-6(ab-1/2a²b)+4ab]-2ab
-9a^3+12a^2b-6ab^2
a^3-6a^b+9ab^2分解因式
