(3a-4b)(5a-6b)+(7a-8b)(5a-6b)分解因式得
(3a-4b)(5a-6b)+(7a-8b)(5a-6b)分解因式得
(3a-4b)(5a-6b)+(7a-8b)(5a-6b)分解因式得
(3a-4b)(5a-6b)+(7a-8b)(5a-6b)
=(5a-6b)(3a-4b+7a-8b)
=(5a-6b)(10a-12b)
=2(5a-6b)^2
(3a-6b)/(a+b) - (5a-6b)/(a-b) - (4a-5b)/(a+b) - (7a-8b)/(a-b) 快
(3a-6b/a+b)-(5a-6b/a-b)-(4a-5b/a+b)-(7a-8b/b-a)
初二分式的加减法2a-b-c/(a-b)(a-c)+ 2b-c-a/(b-c)(b-a)+ 2c-b-a/(c-b)(c-a)3a-6b/a+b- 5a-6b/a-b- 4a-5b/a+b+ 7a-8b/b-a注:有空格的地方是下一个分式
5(a*a*b-3*a*a*b)-2*(a*a*b-7*a*b*b)
a+b分之3a-6b-a-b分之5a-6b-a+b分之4a-5b-b-a分之7a-8b
(3a-4b)(5a-6b)+(7a-8b)(5a-6b)分解因式得
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=()
已知A=5a-3b,B=-6a+4b,则A-B等于 A.-a+b,B=11a+b C.11a-7b D -a-7b
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=2026
一个长方形操场的周长是6a+8a,其中一条边长是2a+3b,则另一条边长是 A.a+b B.a+7b C.2a+2b D.4a+5b
(3a+4b)(7a-8b)+(11a+2b)(8a-7a)
2a-{7b+[4a-7b-(2a-6a-4b)]-3a
(3a-4b)(7a-8b)+(11a-12b)(8b-7a)
(a+2b)(2a+4b)(3a+6b)(4a+8b)
化简8(a-b)2+4(a-b)+5(b-a)-6(b-a)2
8(a-b)²+4(a-b)+5(b-a)-6(b-a)²
已知A=5a-3b,B=-6a+4b,A-B=?
2(a+b)-[4(a+b)-3(a+b)]一[5(a-b)+(a-b)]过程
