1. **State the problem:** Simplify the expression $$10p - \frac{8}{p^2 - 50p + 44}$$ and express it as a single fraction in simplest form.
2. **Factor the denominator:** The quadratic in the denominator is $$p^2 - 50p + 44$$.
We look for factors of 44 that add up to -50. Since 44 is positive and the middle term is negative, both factors are negative.
Factors of 44: 1, 2, 4, 11, 22, 44.
Try -2 and -22: $$-2 + (-22) = -24$$ (not -50).
Try -44 and -1: $$-44 + (-1) = -45$$ (not -50).
Try -22 and -2: already tried.
Try -11 and -4: $$-11 + (-4) = -15$$ (no).
Try -1 and -44: no.
Try -50 and something? No.
Since no integer factors, use quadratic formula:
$$p = \frac{50 \pm \sqrt{(-50)^2 - 4 \cdot 1 \cdot 44}}{2} = \frac{50 \pm \sqrt{2500 - 176}}{2} = \frac{50 \pm \sqrt{2324}}{2}$$
Since it does not factor nicely, keep denominator as is.
3. **Rewrite the expression as a single fraction:**
Express $$10p$$ as $$\frac{10p(p^2 - 50p + 44)}{p^2 - 50p + 44}$$ to have common denominator:
$$10p = \frac{10p(p^2 - 50p + 44)}{p^2 - 50p + 44}$$
4. **Combine the fractions:**
$$10p - \frac{8}{p^2 - 50p + 44} = \frac{10p(p^2 - 50p + 44) - 8}{p^2 - 50p + 44}$$
5. **Expand the numerator:**
$$10p(p^2 - 50p + 44) = 10p^3 - 500p^2 + 440p$$
So numerator is:
$$10p^3 - 500p^2 + 440p - 8$$
6. **Final expression:**
$$\frac{10p^3 - 500p^2 + 440p - 8}{p^2 - 50p + 44}$$
7. **Check for common factors:**
Try to factor numerator:
Look for common factor: none (10p^3, -500p^2, 440p, -8) share factor 2.
Factor out 2:
$$2(5p^3 - 250p^2 + 220p - 4)$$
No obvious factorization further.
Denominator does not factor nicely.
Therefore, the simplest form is:
$$\boxed{\frac{10p^3 - 500p^2 + 440p - 8}{p^2 - 50p + 44}}$$
