Question
Solve algebraically for all values of xx:
**Problem Statement:**

Solve algebraically for all values of \( x \):

\[ 5x^4 - 6x^3 = 0 \]

**Solution:**

1. **Factor the equation:**
   - Take out the common factor, \( x^3 \):
     \[
     x^3(5x - 6) = 0
     \]

2. **Set each factor to zero and solve:**
   
   - \( x^3 = 0 \):
     - Solution: \( x = 0 \)
   
   - \( 5x - 6 = 0 \):
     - Solve for \( x \): \( 5x = 6 \)
     - \( x = \frac{6}{5} \)

**Conclusion:**

The values of \( x \) that satisfy the equation are:

\[ x = 0 \quad \text{and} \quad x = \frac{6}{5} \]
