Answer 3

To evaluate the expression -(3-у)²+у(у+2) at у = -1/8, we substitute the given value into the expression. Let's do the calculations step by step:

First, substitute у = -1/8 into -(3-у)²: -(3 - (-1/8))² = -(3 + 1/8)² = -(3⅛)² = -(25/8)² = -(625/64) = -9.765625

Next, substitute у = -1/8 into у(у+2): (-1/8)((-1/8)+2) = (-1/8)(-1/8+16/8) = (-1/8)(15/8) = -15/64

Now, add the two results together: -9.765625 + (-15/64) = -625/64 - 15/64 = -640/64 = -10

Therefore, when у = -1/8, the expression -(3-у)²+у(у+2) evaluates to -10.
