Why should it be equal to -36????
di+do=36. You can see it in the picture.
do can be either 12 or 24.
If do=12, di =24.
If do=24, di=12.
cuz ehild i was thinking that for x^2-36x+288=0 since a=1 b=-36 c=288 so dont that mean that i have to find 2 values that add to equal -36 and multiply to give us 288?
