    i would start by grouping them into sections because they’re all like terms.
    (-7c2-c2) = -8c2
    (-5c2-2c2)= -7c2
    (8c2-9c2) =-c2
    then add them all together.
    -8c2-7c2-c2
    since they’re all negative you can add them together but don’t forget the negative.
    8+7=15
    15+1 = 16
    add the negative back in to get -16c2
