Quizplus · Accepted Answer

This cubic equation can be solved by factoring or using the rational root theorem. Factoring, we find that $x = -5$, $x = 5$, and $x = -\frac{1}{9}$ are solutions, making option A correct.

Solve - 9x3+x2−225x−25=09 x ^ { 3 } + x ^ { 2 } - 225 x - 25 = 09x3+x2−225x−25=0

Solve
- $9 x ^ { 3 } + x ^ { 2 } - 225 x - 25 = 0$
