    Think of products that equal to 72

    When you find those numbers add or subtract those numbers to see if you get the value in the center

    9*8=72

    Make 9 a negative (-9) and 8 a negative 9 in the first parenthesis and positive 8 in the second you will get

    -8x+9x=-x

    (x-9) (x+8)
