Answer 1

To solve the quadratic equation \( 46x^2 - 138x = 0 \) by factoring out the greatest common factor (GCF), we first identify the GCF of the terms.

The GCF of \( 46x^2 \) and \( -138x \) is \( 46x \). So, we can factor it out:

\[ 46x(x - 3) = 0 \]

Now, we set each factor equal to zero:

1. \( 46x = 0 \) which gives \( x = 0 \)
2. \( x - 3 = 0 \) which gives \( x = 3 \)

Thus, the solutions to the quadratic equation are:

\[ x = 0 \quad \text{and} \quad x = 3 \]

Therefore, the correct response is:

The solutions are \( x = 0 \) and \( x = 3 \).
