Gio is solving the quadratic equation by completing the square. 5 x squared plus 15 x minus 4 is equal to 0 What should Gio do first?

First move the constant term, −4, to the other side by adding 4 to both sides: 5x² + 15x = 4. This isolates the constant on one side and leaves the variable terms together, ready for the next steps in completing the square. The correct choice is “Isolate the constant.”
