Answer 2

To simplify the expression, let's expand and combine like terms:

(с-4)(3с+5)-(4-с)(с+2)

Expanding the first term: = (3с^2 + 5с - 12с - 20) - ((4c - с^2 + 8 - 2с)

Simplifying the expression further: = 3с^2 + 5с - 12с - 20 - 4c + с^2 - 8 + 2с

Combining like terms: = 3с^2 + с^2 + 5с - 12с + 2с - 4c - 20 - 8

Combining like terms again: = 4с^2 - 5с - 12c - 28

Therefore, the simplified expression is 4с^2 - 5с - 12c - 28.
