Answer 2

Let's simplify the given expression step by step.

First, let's expand the left side of the equation using the distributive property:

(у² - 3у + 9) × (у + 3) = у² × у + у² × 3 - 3у × у - 3у × 3 + 9 × у + 9 × 3

Simplifying further:

= у³ + 3у² - 3у² - 9у - 3у + 9у + 27

Combining like terms:

= у³ - 3у + 27

The simplified expression on the left side of the equation is у³ - 3у + 27.

Therefore, the given equation (у² - 3у + 9) × (у + 3) = 6у + у³ simplifies to у³ - 3у + 27 = 6у + у³.
