Answer 2

To find the difference in simplest form, we first need to combine the fractions in the expression.

The expression given is:
(n^2 + 3n + 2) / (n^2 + 6n + 8) - 2n / (n + 4)

To combine the fractions, we need a common denominator. The common denominator for the two fractions is: (n^2 + 6n + 8)(n + 4).

Rewriting the fractions with the common denominator, we get:
[(n^2 + 3n + 2)*(n + 4) - 2n*(n^2 + 6n + 8)] / (n^2 + 6n + 8)(n + 4)

Expanding the numerators, we get:
[n^3 + 7n^2 + 14n + 8 - 2n^3 - 12n^2 - 16n] / (n^2 + 6n + 8)(n + 4)

Combining like terms in the numerator, we get:
[-n^3 - 5n^2 - 2n + 8] / (n^2 + 6n + 8)(n + 4)

Therefore, the simplified form of the expression is:
(-n^3 - 5n^2 - 2n + 8) / (n^2 + 6n + 8)(n + 4)

Answer 3

Let's double-check the simplification of the expression:

The expression given is:
(n^2 + 3n + 2) / (n^2 + 6n + 8) - 2n / (n + 4)

To simplify this expression, we need a common denominator of (n^2 + 6n + 8)(n + 4).

The expression can be rewritten with a common denominator as:
[(n^2 + 3n + 2)(n + 4) - 2n(n^2 + 6n + 8)] / (n^2 + 6n + 8)(n + 4)

Expanding the numerators:
[(n^3 + 4n^2 + 3n + 2n + 8) - (2n^3 + 12n^2 + 16n)] / (n^2 + 6n + 8)(n + 4)

Combining like terms:
[n^3 + 4n^2 + 3n + 2n + 8 - 2n^3 - 12n^2 - 16n] / (n^2 + 6n + 8)(n + 4)

This simplifies to:
(-n^3 - 8n^2 - 11n + 8) / (n^2 + 6n + 8)(n + 4)

Therefore, the corrected simplified form of the expression is:
(-n^3 - 8n^2 - 11n + 8) / (n^2 + 6n + 8)(n + 4)
