Question

(iv) 2 y3+ y2 - 2y-1 factories​

Answer 1

$\star\:\:\:\bf\large\underline\blue{Question:-}$

• Factorise the polynomial.

$\star\:\:\:\bf\large\underline\blue{Solution:-}$

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

$= {y}^{2} (2y - 1) - 1(2y - 1)$

$= ( {y}^{2} - 1)(2y - 1)$

$= ( {y }^{2} - {1}^{2} )(2y - 1)$

$= (y + 1)(y - 1)(2y - 1)$

$\star\:\:\:\bf\large\underline\blue{Answer:-}$

• $(y + 1)(y - 1)(2y - 1)$
