    Answer:x=-2 and - 8

    Step-by-step explanation:

    X^2+10x+16=0

    X^2+8x+2x+16=0

    X (x+8) + 2 (x+8) = 0

    (X+2) (x+8) = 0

    X+2=0 and x+8=0

    X=-2 and x=-8

    (x + 8) (x + 2)

    Step-by-step explanation:

    Given

    x² + 10x + 16

    Consider the factors of the constant term ( + 16) which sum to give the coefficient of the x - term ( + 10)

    The factors are + 8 and + 2, since

    8 * 2 = 16 and 8 + 2 = 10, thus

    x² + 10x + 16 = (x + 8) (x + 2) ← in factored form
