1. **Stating the problem:** Simplify the expression $$\frac{y(alla 3)+\frac{7}{4}y+1}{y+\frac{1}{2}}$$. It seems "alla 3" means $y^3$, so the expression is $$\frac{y^3 + \frac{7}{4}y + 1}{y + \frac{1}{2}}$$.
2. **Rewrite the expression clearly:**
$$\frac{y^3 + \frac{7}{4}y + 1}{y + \frac{1}{2}}$$
3. **Find a common denominator in numerator terms if needed:**
Rewrite numerator as $$y^3 + \frac{7}{4}y + 1 = y^3 + \frac{7}{4}y + \frac{4}{4}$$
4. **Try polynomial division or factorization:**
We want to divide numerator by denominator:
$$\frac{y^3 + \frac{7}{4}y + 1}{y + \frac{1}{2}}$$
5. **Multiply numerator and denominator by 4 to clear fractions:**
$$\frac{4y^3 + 7y + 4}{4y + 2}$$
6. **Perform polynomial division:**
Divide $4y^3 + 7y + 4$ by $4y + 2$.
- First term: $\frac{4y^3}{4y} = y^2$
- Multiply divisor by $y^2$: $4y^3 + 2y^2$
- Subtract: $(4y^3 + 7y + 4) - (4y^3 + 2y^2) = -2y^2 + 7y + 4$
- Next term: $\frac{-2y^2}{4y} = -\frac{1}{2}y$
- Multiply divisor by $-\frac{1}{2}y$: $-2y^2 - y$
- Subtract: $(-2y^2 + 7y + 4) - (-2y^2 - y) = 8y + 4$
- Next term: $\frac{8y}{4y} = 2$
- Multiply divisor by $2$: $8y + 4$
- Subtract: $(8y + 4) - (8y + 4) = 0$
7. **Result of division:**
$$y^2 - \frac{1}{2}y + 2$$
8. **Final answer:**
$$\boxed{y^2 - \frac{1}{2}y + 2}$$
