Lie is solving the quadratic equation by completing the square.3x2 + 18x – 8 = 0 3x2 + 18x = 8

The equation is already arranged with the constant on the right: 3x² + 18x = 8. To prepare to complete the square, factor 3 out of the terms containing x, giving 3(x² + 6x) = 8. So the next step is to factor 3 out of the variable terms.
