Answer 2

To simplify the given expression, let's start by applying the distributive property and then combine like terms:

(х + 2)(х - 5) - 3х(1 - 2х)

First, expand each term:

(х * х) + (х * -5) + (2 * х) + (2 * -5) - (3х * 1) - (3х * -2х)

Now, simplify each term:

х^2 - 5х + 2х - 10 - 3х + 6х^2

Combine like terms:

(х^2 + 6х^2) + (-5х + 2х - 3х) - 10

7х^2 - 6х - 10

So, the simplified expression is 7х^2 - 6х - 10.
