Answer:
\((xy^2-5)\text{ is one factor of above polynomial}\)
Step-by-step explanation:
Given the polynomial
\(x^3y^2+8xy^2-5x^2-40\)
we have to select the option which is one of the factor of above polynomial.
\(x^3y^2+8xy^2-5x^2-40\)
\(xy^2(x^2+8)-5(x^2+8)\)
\((xy^2-5)(x^2+8)\)
\(\text{Hence, }(xy^2-5)\text{ is one factor of above polynomial}\)
∴ Option 3 is correct
