Answer 2

To simplify the given expressions, let's find their common factors and cancel them out:

1. y^2 + y / y^2

The numerator and denominator have a common factor of y. We can cancel out y:

= y(y + 1) / y^2

2. a^2 - 2a / a^2 - 4

The numerator and denominator do not have any common factors. So we cannot simplify this fraction any further.

The simplified expressions are:

1. y(y + 1) / y^2

2. a^2 - 2a / a^2 - 4
