Làm tính chia:
[3(x – y)\(^4\) + 2(x – y)\(^3\) – 5(x – y)\(^2\)] : (y – x)\(^2\)
[3(x – y)\(^4\) + 2(x – y)\(^3\) – 5(x – y)\(^2\)] : (y – x)\(^2\)
= \([3(x - y)^4+2(x - y)^3-5(x - y)^2]:(x - y)^2\)
= \(3(x - y)^4 : (x - y)^2+2(x - y)^3:(x - y)^2-5(x - y)^2:(x - y)^2\)
= \(3(x - y)^2 + 2(x - y) -5\)
