分式计算,((x+1)²(1-x)²)/((x²-1)²)÷((x-1)²)/(x²-1)
问题描述:
分式计算,((x+1)²(1-x)²)/((x²-1)²)÷((x-1)²)/(x²-1)
答
((x+1)²(1-x)²)/((x²-1)²)÷((x-1)²)/(x²-1)
= [(x+1)²(x-1)²/(x+1)²(x-1)²][(x²-1)/(x-1)²]
=(x+1)/(x-1)
答
原式=[(x+1)²(x-1)²/(x+1)²(x-1)²][(x²-1)/(x-1)²]
=1*(x+1)(x-1)/(x-1)²
=(x+1)/(x-1)
答
((x+1)²(1-x)²)/((x²-1)²)÷((x-1)²)/(x²-1)=((x+1)²(1-x)²)(x²-1)/((x²-1)²)((x-1)²)=((x+1)²)/((x...
