Answer 2

To simplify the given expression $(3y - 5)(y - 2) - 4(2y - 1) + 9(y - 2)$, let's follow these steps:

1. Expand the expressions using the distributive property.
2. Simplify by combining like terms.

Let's start with expanding the expressions:

$(3y - 5)(y - 2)$ expands to $3y^2 - 6y - 5y + 10$

$- 4(2y - 1)$ expands to $-8y + 4$

$9(y - 2)$ expands to $9y - 18$

Now, let's simplify and combine like terms:

$3y^2 - 6y - 5y + 10 - 8y + 4 + 9y - 18$

Combine the $y^2$ and $y$ terms:

$3y^2 - 19y - 4$

So, the simplified expression is $3y^2 - 19y - 4$.
