`\huge\underline{ \underline{Solution :-}}`

`( {y}^(2) + (5)/(7) )( {y}^(2) - (14)/(5) )`

To solve, use the algebraic identity ➺

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

`( {y}^(2) + (5)/(7) )( {y}^(2) - (14)/(5) ) \\ = ({y}^(2)) ^(2) + ( (5)/(7) + - (14)/(5) ) {y}^(2) + (5)/(7) * - (14)/(5) \\ = {y}^(4) - (73)/(35) {y}^(2) - 2`
