Answer 1

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

The GCF of \( 46x^2 \) and \( -138x \) is \( 46x \). We can factor this out:

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

Now, we can set each factor to zero:

1. \( 46x = 0 \)

   • Dividing both sides by 46 gives \( x = 0 \).

2. \( x - 3 = 0 \)

   • Adding 3 to both sides gives \( x = 3 \).

Thus, the solutions are \( x = 0 \) and \( x = 3 \).

The correct response is: The solutions are x=0 and x=3.
