question 155

Multiple Choice

Evaluate the discriminant for the equation. Then use it to predict the number of distinct solutions, and whether they are
rational, irrational, or nonreal complex.
- $- 7 a x ^ { 3 } \left( - 10 a x ^ { 3 } + 5 x ^ { 2 } + 1 \right)$

• A) \(70 a x ^ { 9 } - 35 a x ^ { 6 } - 7 a x ^ { 3 }\)
• B) \(- 70 a ^ { 2 } x ^ { 6 } + 35 a x ^ { 5 } + 7 a x ^ { 3 }\)
• C) \(70 a ^ { 2 } x ^ { 6 } - 35 a x ^ { 5 } - 7 a x ^ { 3 }\)
• D) \(- 70 a ^ { 2 } x ^ { 9 } + 35 a x ^ { 6 } + 7 a x ^ { 3 }\)
