    Answer:

    x = -10, 0

    Step-by-step explanation:

    Step 1: Write quadratic

    x² + 10x = 0

    Step 2: Complete the Square

    x² + 10x + 25 = 25

    (x + 5)² = 25

    Step 3: Square root both sides

    x + 5 = ±5

    Step 4: Subtract 5 on both sides

    x = -5 ± 5

    x = -10, 0
