Answer
$6x^3y+2xy-10x$.
Work Step by Step
The given expression is
$=(36x^4y^3+12x^2y^3-60x^2y^2)\div (6xy^2)$
Rewrite in vertical format.
$=\frac{36x^4y^3+12x^2y^3-60x^2y^2}{6xy^2}$
Divide each term of the polynomial by the monomial.
$=\frac{36x^4y^3}{6xy^2}+\frac{12x^2y^3}{6xy^2}-\frac{60x^2y^2}{6xy^2}$
Simplify (Cancel common terms).
$=6x^3y+2xy-10x$.
