Solve the Question step by step ?

Answer 1

Step-by-step explanation:

Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd.

$\tt\red{\implies \frac{3{x}^{2}}{5}+\frac{8xy}{15}+\frac{yx}{8}+\frac{{y}^{2}}{9}}$

$\tt\pink{\implies \frac{3{x}^{2}}{5}+(\frac{8xy}{15}+\frac{xy}{8})+\frac{{y}^{2}}{9}}$

$\tt\orange{\implies \frac{3{x}^{2}}{5}+\frac{79xy}{120}+\frac{{y}^{2}}{9}}$

therefore,Correct Option Is (A).
