Answer 1

y3+6y^2-16y sorry

Answer 2

?

I'm confused...

Answer 3

Factoring of cubing trinomial with no constant terms is quite easy.

Just factor out y, then you have a quadratic trinomial to factor.

⇒ y³ + y² − 56y

⇒ y (y² + y − 56)

To factor quadratic, find 2 number whose sum is 1 and product is −56

These two numbers are 8 and −7.

⇒ y (y+8) (y−7)

Answer is A
