Answer 2

It looks like there might be a typo in your expression. It appears that you intended to write:

(у-2)(у + 2у) + 8

In this case, let's simplify the expression:

(у-2)(у + 2у) + 8

First, simplify the expression inside the first set of parentheses:

у + 2у = 3у

Now, your expression becomes:

(у - 2)(3у) + 8

Next, distribute 3у into the first set of parentheses:

3у(у - 2) + 8

Now, multiply 3у by each term inside the first set of parentheses:

3у * у = 3у^2 3у * (-2) = -6у

So, the expression becomes:

3у^2 - 6у + 8

That's the simplified form of the expression: 3у^2 - 6у + 8.
