Factorize 急急急!
發問:
題目: Factorize 8(a2-a)^3+42(a2-a)2-36a2+36a 要有步驟。 更新: 答案係:2a(a-1)(a2-a+6)(2a+1)(2a-3) 我只係想要步驟!
最佳解答:
其他解答:
8(a2-a)^3+42(a2-a)2-36a2+36a =8a^6-8a^3+42a^4-42a^2-36a^2+36a =8a^6+42a^4-8a^3-78a^2+36a =8a^3(a^3-1)+6a(7a^3-13a+6) I am not sure if it isn't correct.Anyway,I hope I can really help you.^^

=8(a2-a)^3+42(a2-a)^2-36(a2-a) =2(a2-a)[4(a2-a)^2+21(a2-a)-18] =2a(a-1)[4(a2-a)-3][(a2-a)+6] =2a(a-1)[(a2-a)+6][4a2-4a-3] =2a(a-1)(a2-a+6)(2a+1)(2a-3)其他解答:
