Question

Thực hiện phép chia:

\(\left(x^3y+xy^3+xy\right):y\left(x^2+y^2+1\right)\)

Answer 1

\(\left(x^3y+xy^3+xy\right):y\left(x^2+y^2+1\right).\)

\(=xy.\left(x^2+y^2+1\right):y.\left(x^2+y^{2+}1\right)\)

\(=\left(xy:y\right).\left(x^2+y^2+1\right)^2\)

\(=x.\left(x^2+y^2+1\right)^2\)

Answer 2

\(=\frac{\left[xy\left(x^2+y^2+1\right)\right]}{y.\left(x^2+y^2+1\right)}\)

\(=x\)
