today is my paper please give answer​

Answer 1

Answer :

4.

Now, 27p³ - 1/216 - 9/2 p² + 1/4 p

= 27p³ - 9/2 p² + 1/4 p - 1/216

= (3p)³ - 3 (3p)² (1/6) + 3 (3p) (1/6)² - (1/6)³

= (3p - 1/6)³

= (3p - 1/6) (3p - 1/6) (3p - 1/6) ,

which is the required factorization.

5.

Now, 2y³ + y² + 2y - 1

= 2y³ + 2y + y² - 1

= 2y (y² + 1) + 1 (y² - 1)

However we proceed, factorization isn't possible.
