The nature of the roots can be determined by the determinant of the equation. The determinant is:
b² - 4ac
If this is positive, there are two roots
If this is 0, there is only one root
If this is negative, there are complex roots
Answer:
Step-by-step explanation:
<u>80:50:20 or 8:5:2. 8 ÷ 15 * 30 = 16 = 16 - 10 = 6. This is the solution.</u>
- Option A. 30 + 10 = 40. Incorrect. The solution is unequal to this.
- Option B. 30 + 9 = 39. Incorrect. The solution is unequal to this.
- Option C. 30 + 8 = 38. Incorrect. The solution is unequal to this.
- Option D. 30 + 7 = 37. Incorrect. The solution is unequal to this.
- Option E. 30 + 6 = 36. Correct. The solution equals this answer.
<u>Option E will be the answer.</u>
