Answer 1

❀ $\huge\underline{ \underline{Solution :-}}$

$( {y}^{2} + \frac{5}{7} )( {y}^{2} - \frac{14}{5} )$

To solve, use the algebraic identity ➺

• (x + a)( x + b) = x² + (a + b)x + ab

$( {y}^{2} + \frac{5}{7} )( {y}^{2} - \frac{14}{5} ) \\ = ({y}^{2}) ^{2} + ( \frac{5}{7} + - \frac{14}{5} ) {y}^{2} + \frac{5}{7} \times - \frac{14}{5} \\ = {y}^{4} - \frac{73}{35} {y}^{2} - 2$
