Answer

Explanation:

Step1: Recall completing - the - square steps

When completing the square for a quadratic equation of the form (ax^{2}+bx + c=0) ((a\neq0)), if (a\neq1), the first step is to factor out the coefficient of (x^{2}) from the (x) - terms. In the equation (5x^{2}+15x - 4=0), (a = 5), (b = 15), and (c=-4).

Answer:

B. Factor 5 out of the variable terms
