3a^2+2ab-(a-2b)/3+(8a^2-12ab+a-b)/6,其中a=2,b=-3/2
3a^2+2ab-(a-2b)/3+(8a^2-12ab+a-b)/6,其中a=2,b=-3/2
3a^2+2ab-(a-2b)/3+(8a^2-12ab+a-b)/6,其中a=2,b=-3/2
3a²+2ab-(a-2b)/3+(8a²-12ab+a-b)/6
=[9a²+6ab-(a-2b)]/3+(8a²-12ab+a-b)/6
=[18a²+12ab-2(a-2b)]/6+(8a²-12ab+a-b)/6
=(18a²+12ab-2a+4b+8a²-12ab+a-b)/6
=(26a²-a+3b)/6=26×4-2-9/2
=65/4
哎,我是文傻~
(a-b)^3+2ab(a-b)
ab/a+b=3 a-2ab+b/2a-3ab+2b?
3(-ab+2a)-(3a-b)
3(-ab+2a)-(3a-b)
(ab(a^-2ab)-a^2b(a-3b))÷(3a^b)
-2ab乘以(-a^+6a^b-3a+b)
18ab(a-b)^2-12a(b-a)^3
a^3-ab^2 =a (a^2 -b^2) =a(a+b)(a-b)
a^2b-ab+2ab^2-5a^b-4ab+3ab^2化简快
3(-2ab+3a)-(2a-b)+6ab
3(-ab+2a)-(3a-b)+2ab
3(-ab+2a)-(3a-b)+3ab
化简:(-2ab+3a)-(2a-b)+6ab
ab^3+b^2+b-a+1
(a-b)(3ab+2a²b-b³)
a^2-3ab+b^2/ab=( )/ab-3
a^2-3ab+b^2/ab=( )/ab -3
1.(a-b)(a^2+ab+b^3)2.(a-b)(a^3+a^2b+ab^2+b^3)3.(a-b)(a^4+a^3b+a^2b^2+ab^3+b^4)4.(a-b)(a^10+a^9b+a^8b^2+...+ab^9+b^10)5.(X-1)(x^5+x^4+x^3+x^2+1)6.(a-b)(a^n+a^n-1b+a^n-2b^2+...+ab^n-1+b^n)
