[8(a-b)^5-4(a-b)^4+(-a+b)^3]/[2(a-b)^3]
=[8(a-b)^5-4(a-b)^4-(a-b)^3]/[2(a-b)^3]
=8(a-b)^5/[2(a-b)^3]-4(a-b)^4/[2(a-b)^3]-(a-b)^3/[2(a-b)^3]
=4(a-b)^2-2(a-b)-1/2
=4a^2-8ab+4b^2-2a+2b-1/2

(3a-6b)/(a+b) - (5a-6b)/(a-b) - (4a-5b)/(a+b) - (7a-8b)/(a-b (3a-6b/a+b）-(5a-6b/a-b)-(4a-5b/a+b)-(7a-8b/b-a) 4(b-a)(a+b)-(2a-3b)(3a-2b)怎么计算 1.（a-b)^2（b-a)^3(a-b)^-4 (a+2b)(2a+4b)(3a+6b)(4a+8b) 0 a a+b 2a+b 2a+2b 3a+2b 3a+3b 4a+3b 4a+4b 5a+4b 5a+5b …… 求一计算：3a+4b/a-b+3b/b-a-4a/a-b 3a/a-4b +a+b/4b-a -7b/a-4b (2a+b)(2a-b)-3a(4a-3b)+(4a-b)(2a-b) a=5分之3,b=3分之2 2a²(b²-3b)-4b(b²-3a²-a²b)怎么解？因式分解8a^3b^3 12a^4b^2 16a^5b 8a+2b+(5a - b) (5a-3b) -3 (a平方 - 2b)
