Answer:
[tex]\huge \boxed{11x^2 y^3-4xy^2 }[/tex]
Step-by-step explanation:
[tex](4x^2y^3 + 2xy^2 - 2y) - (-7x^2 y^3 + 6xy^2 -2y)[/tex]
Distribute the negative sign to the terms in the bracket.
[tex](4x^2y^3 + 2xy^2 - 2y) +7x^2 y^3 - 6xy^2 +2y[/tex]
Grouping like terms.
[tex](4x^2y^3 +7x^2 y^3) + (2xy^2 - 6xy^2 ) +( - 2y +2y)[/tex]
Combining like terms.
[tex](11x^2 y^3) + (-4xy^2 ) +(0)[/tex]
[tex]11x^2 y^3-4xy^2[/tex]
