Answer 1

Step-by-step explanation:

AS MY UNDERSTANDING OF QUESTION...

$( \frac{2}{5} x^{2} + 3 {y}^{2})(5 {x}^{2} - \frac{4 {y}^{2} }{7} ) \\ \frac{2}{5} {x}^{2} (5 {x}^{2} - \frac{4 {y}^{2} }{7} ) + 3 {y}^{2} (5 {x}^{2} - \frac{4 {y}^{2} }{7} ) \\ 2 {x}^{4} - \frac{8 {x}^{2} {y}^{2} }{35} + 15 {x}^{2} {y}^{2} - \frac{12 {y}^{4} }{7} \\ 2 {x}^{4} - \frac{12 {y}^{4} }{7} + \frac{517 x^{2} {y}^{2} }{35}$

so this will ur ans
