Answer:
Option C. [tex]7xy^{5}+2y^{2}-10[/tex] is the answer.
Step-by-step explanation:
The given fraction is [tex]\frac{21x^{2}y^{6}+6xy^{3}-30xy}{3xy}[/tex].
We have to find the quotient. As we know quotient is the net result of division of any fraction, so we will solve the fraction to get the value of quotient.
[tex]\frac{3xy(7xy^{5}+2y^{2}-10)}{3xy}[/tex]
[tex]7xy^{5}+2y^{2}-10[/tex]
Therefore the quotient is Option C. [tex]7xy^{5}+2y^{2}-10[/tex].
