Thực hiện phép chia: [3(x - y)^5 - 2(x - y)^4 + 3(x - y)2] : 5(x - y)^2
Thực hiện phép chia: [3(x – y)5 – 2(x – y)4 + 3(x – y)2] : 5(x – y)2.
[3(x – y)5 – 2(x – y)4 + 3(x – y)2] : 5(x – y)2
= 3(x – y)5 : 5(x – y)2 – 2(x – y)4 : 5(x – y)2 + 3(x – y)2 : 5(x – y)2
= \(\frac{3}{5}{\left( {x - y} \right)^3} - \frac{2}{5}{\left( {x - y} \right)^2} + \frac{3}{5}\).
