Answer 2

To simplify the expression 5(1 - у)^2 - (3 + у)^2 - 4у^2 + 16у, we can expand the squares and combine like terms:

First, let's expand the squares: 5(1 - у)^2 = 5(1 - 2у + у^2) = 5 - 10у + 5у^2 (3 + у)^2 = (3 + у)(3 + у) = 9 + 6у + у^2

Now let's substitute these expanded forms back into the expression: 5(1 - у)^2 - (3 + у)^2 - 4у^2 + 16у = (5 - 10у + 5у^2) - (9 + 6у + у^2) - 4у^2 + 16у

Expanding further: = 5 - 10у + 5у^2 - 9 - 6у - у^2 - 4у^2 + 16у = (5 - 9) + (-10у - 6у + 16у) + (5у^2 - у^2 - 4у^2) = -4у + 0у + 0у^2 = -4у

Therefore, the simplified expression is -4у.
