Question: Which of the following is the proper ordering of the polynomial
14x^3 - 6x^7 + 20x^5 + 5x^2?
6x^7 + 20x^5 - 14x^3 + 5x^2
20x^5 + 14x^3 + 5x^2 - 6x^7
20x^5 + 14x^3 - 6x^7 + 5x^2
-6x^7 + 20x^5 + 14x^3 + 5x^2
1. **State the problem:** We need to find the proper ordering of the polynomial $$14x^3 - 6x^7 + 20x^5 + 5x^2$$.
2. **Recall the rule for ordering polynomials:** Polynomials are typically ordered in descending powers of $$x$$, starting from the highest exponent to the lowest.
3. **Identify the powers of $$x$$ in each term:**
- $$14x^3$$ has power 3
- $$-6x^7$$ has power 7
- $$20x^5$$ has power 5
- $$5x^2$$ has power 2
4. **Order the terms from highest to lowest power:**
- Highest power is $$7$$, so $$-6x^7$$ comes first
- Next is power $$5$$, so $$20x^5$$ comes second
- Then power $$3$$, so $$14x^3$$ comes third
- Finally power $$2$$, so $$5x^2$$ comes last
5. **Write the polynomial in proper order:**
$$-6x^7 + 20x^5 + 14x^3 + 5x^2$$
6. **Compare with the given options:** The correct ordering matches the option:
- $$-6x^7 + 20x^5 + 14x^3 + 5x^2$$
**Final answer:** $$-6x^7 + 20x^5 + 14x^3 + 5x^2$$
