Answer 1

1) -4*(5Х-У)-5Х*(-6+У-12Х)=-20Х+4У+30Х-5ХУ+60Х^2=60X^2-5ХУ+10Х+4У.

Answer 2

Problem:

We are given the expression -4(-5x-y)-5x(-6+y-12x) and we need to simplify it by expanding the brackets.

Solution:

To simplify the expression, we will start by expanding the brackets and then combine like terms.

Expanding the first set of brackets, we get: -4(-5x-y) = 20x + 4y

Expanding the second set of brackets, we get: -5x(-6+y-12x) = 30x - 5xy + 60x^2

Now, let's combine the like terms: 20x + 4y + 30x - 5xy + 60x^2

Combining the x terms, we get: 20x + 30x + 60x^2 = 110x + 60x^2

The final simplified expression is: 110x + 60x^2 + 4y

Therefore, the simplified form of the expression -4(-5x-y)-5x(-6+y-12x) is 110x + 60x^2 + 4y.
