Answer :

To simplify the expression [tex]\( y = \frac{-4 - x^3}{2x^2} \)[/tex], let's proceed through a detailed, step-by-step solution.

1. Identify the expression to simplify:
[tex]\[ y = \frac{-4 - x^3}{2x^2} \][/tex]

2. Separate the numerator:
We can rewrite the fraction by breaking up the numerator over the common denominator:
[tex]\[ y = \frac{-4}{2x^2} + \frac{-x^3}{2x^2} \][/tex]

3. Simplify each term individually:
- For the first term, [tex]\(\frac{-4}{2x^2}\)[/tex]:
[tex]\[ \frac{-4}{2x^2} = \frac{-4}{2} \cdot \frac{1}{x^2} = -2 \cdot \frac{1}{x^2} = \frac{-2}{x^2} \][/tex]

- For the second term, [tex]\(\frac{-x^3}{2x^2}\)[/tex]:
[tex]\[ \frac{-x^3}{2x^2} = -\frac{x^3}{2x^2} \][/tex]
We can simplify the power of [tex]\( x \)[/tex]:
[tex]\[ \frac{x^3}{x^2} = x^{3-2} = x^1 = x \][/tex]
So, we have:
[tex]\[ -\frac{x^3}{2x^2} = -\frac{x}{2} \][/tex]

4. Combine the simplified terms:
Putting both simplified terms together, we get:
[tex]\[ y = \frac{-2}{x^2} - \frac{x}{2} \][/tex]

Therefore, the simplified form of the expression [tex]\( y = \frac{-4 - x^3}{2x^2} \)[/tex] is:
[tex]\[ y = \frac{-2}{x^2} - \frac{x}{2} \][/tex]
