Question

$2y {3} + y {2} - 2y - 1$

Answer 1

Hiii !!! ☺

${2y}^{3 \: } + \: {y}^{2} \: \: - 2y \: - \: 1 \\ = > \: {y}^{2}( \: 2y \: + \: 1) \: - 1(2y \: + 1) \\ = > ({y}^{2} - \: 1) \: (2y \: + \: 1)$

✴ By taking common we can easily factorise it.......

Thanks.....☺

Answer 2

HELLO.......FRIEND!!

THE ANSWER IS HERE,

$= > \: 2 {y}^{3} + {y}^{2} - 2y - 1$

$= > \: {y}^{2} (2y + 1) - 1(2y + 1)$

$= > \: (2y + 1)( {y}^{2} - 1)$


:-)Hope it helps u.
