To solve the equation \( 27x^2 - 9x = 0 \) by factoring, we can first factor out the greatest common factor (GCF) from the terms on the left side of the equation.
1. Identify the GCF of \( 27x^2 \) and \( -9x \), which is \( 9x \).
2. Factor out \( 9x \):
\[
9x(3x - 1) = 0
\]
Now, we set each factor equal to zero and solve for \( x \):
1. \( 9x = 0 \)
- Dividing both sides by 9 gives \( x = 0 \).
2. \( 3x - 1 = 0 \)
- Adding 1 to both sides gives \( 3x = 1 \).
- Dividing both sides by 3 gives \( x = \frac{1}{3} \).
Thus, the solutions are:
\[
x = 0, \frac{1}{3}
\]
So, we can write the final answer as:
**Part 1:**
\[
x = 0, \frac{1}{3}
\]
