Answer:
[tex]\begin{equation*} 5xy^2+15x-y-1 \end{equation*}[/tex]Explanation:
Given the sum:
[tex]\left(2xy^2+15x−6\right)+(3xy^2−y+5)[/tex]First, remove the brackets:
[tex]=2xy^2+15x-6+3xy^2-y+5[/tex]Next, rearrange to bring the like terms together:
[tex]=2xy^2+3xy^2+15x-y-6+5[/tex]Combine like terms:
[tex]=5xy^2+15x-y-1[/tex]The result of the sum is:
[tex]\begin{equation*} 5xy^2+15x-y-1 \end{equation*}[/tex]
