Answer

Explanation:

Step1: Recall completing - the - square steps

When solving a quadratic equation (ax^{2}+bx + c=0) ((a\neq0)) by completing the square, the first step is to isolate the constant term on one side of the equation. For the equation (5x^{2}+15x - 4=0), we want to get the form (5x^{2}+15x=4).

Answer:

Isolate the constant.
