    B.) why Factor p + 12r - 6, I did not do that below.

    Step-by-step explanation:

    r^2+12r-6=0

    solve:

    r^2 + 12 r + 36 - 36 - 6 = 0

    factor the trinomial by completing the square.

    (r + 6) ^2 - 42 = 0

    (r + 6) ^2 = 42

    r + 6 = root (42) or r + 6 = - root (42)

    r = - 6 + root (42) or r = - 6 - root (42)
