Answer :

To simplify the expression [tex]\(\frac{-14 m^2 + 4 m n - m^3 n^2}{2 m n}\)[/tex], follow these steps:

1. Write down the original expression:

[tex]\[ \frac{-14 m^2 + 4 m n - m^3 n^2}{2 m n} \][/tex]

2. Break down the numerator and distribute the denominator:
Every term in the numerator can be divided individually by the denominator [tex]\(2 m n\)[/tex].

[tex]\[ \frac{-14 m^2}{2 m n} + \frac{4 m n}{2 m n} - \frac{m^3 n^2}{2 m n} \][/tex]

3. Simplify each term individually:

- For the first term:

[tex]\[ \frac{-14 m^2}{2 m n} = \frac{-14 m^2}{2 m n} = -7 \frac{m^2}{m n} = -7 \frac{m}{n} \][/tex]

- For the second term:

[tex]\[ \frac{4 m n}{2 m n} = \frac{4 m n}{2 m n} = \frac{4}{2} = 2 \][/tex]

- For the third term:

[tex]\[ \frac{m^3 n^2}{2 m n} = \frac{m^3 n^2}{2 m n} = \frac{m^{3-1} n^{2-1}}{2} = \frac{m^2 n}{2} \][/tex]

4. Rewrite the simplified terms together:

- From the first term, we have [tex]\(-7 \frac{m}{n}\)[/tex]
- From the second term, we have [tex]\(2\)[/tex]
- From the third term, we have [tex]\(\frac{m^2 n}{2}\)[/tex]

[tex]\[ \frac{-14 m^2 + 4 m n - m^3 n^2}{2 m n} = -7 \frac{m}{n} + 2 - \frac{m^2 n}{2} \][/tex]

5. Combine the simplified terms into one expression:

[tex]\[ -\frac{m^2 n}{2} - 7 \frac{m}{n} + 2 \][/tex]

So, the final simplified expression is:

[tex]\[ -\frac{m^2 n}{2} - \frac{7 m}{n} + 2 \][/tex]
