Question

【3(x-y)的4次方(x+y)的5次方-6(x-y)的3次方(x+y)的4次方】÷【3(x-y)²(x+y)的3次方】

过程计算

Answer 1

[3(x-y)的4次方(x+y)的5次方-6(x-y)的3次方(x+y)的4次方]÷[3(x-y)²(x+y)的3次方]
={3(x-y)^3(x+y)^4[(x-y)*(x+y)-2]}÷[3(x-y)²(x+y)^3]
=[(x-y)(x+y)[(x-y)*(x+y)-2]

Answer 2

【3(x-y)的4次方(x+y)的5次方-6(x-y)的3次方(x+y)的4次方】÷【3(x-y)²(x+y)的3次方】
=(x-y)²(x+y)²-2(x-y)(x+y)
=(x-y)(x+y)[(x-y)(x+y)-2]
