    Minus 16x both sides and add 28 to both sides

    x^2-16x+28=0

    factor

    hmm, what 2 numbers multiply to 28 and add to - 16

    hmm

    1 and 28? nope

    2 and 14? yep

    since middle term is negative and last tem is positive, both of the factors are negative

    (x-14) (x-2) = 0

    set each to zero

    x-14=0

    x=14

    x-2=0

    x=2

    x=2 and 14
