To solve the equation \( 3x^2 - 18x = 0 \), you can start by factoring the left-hand side:
-
Factor out the common term, which is \( 3x \): \[ 3x(x - 6) = 0 \]
-
Set each factor equal to zero: \[ 3x = 0 \quad \text{or} \quad x - 6 = 0 \]
-
Solve for \( x \):
- From \( 3x = 0 \): \[ x = 0 \]
- From \( x - 6 = 0 \): \[ x = 6 \]
Thus, the solutions for \( x \) are \( x = 0 \) and \( x = 6 \).
