    To solve the solution set of the problem, we can factor the expression given into x * (7x + 3) = 0. This dissects the equation into two parts:

    x = 0

    and

    7x + 3 = 0x = - 3/7

    Hence the answer to this problem must be B. {0, - 3/7}

    7x² + 3x = 0

    x (7x + 3) = 0 ⇔ x = 0 or 7x + 3 = 0 |subtract 3 from both sides

    x = 0 or 7x = - 3 |divide both sides by 7

    x = 0 or x = - 3/7

    Answer: B. {0; - 3/7}
