To solve the quadratic equation \( 46x^2 - 138x = 0 \) by factoring out the greatest common factor (GCF), we first factor out \( 46x \):
\[ 46x(x - 3) = 0 \]
Now, we can set each factor equal to zero:
- \( 46x = 0 \) implies \( x = 0 \)
- \( x - 3 = 0 \) implies \( x = 3 \)
Thus, the solutions to the equation are:
\[ x = 0 \quad \text{and} \quad x = 3 \]
The correct answer is:
The solutions are x=0 and x=3.
