let one part be x and the other be y
x+y=39
xy=324
x=39-y
(39-y)y=324
39y-y^2=324
y^2-39y+324=0
y^2-27y-12y+324=0
y(y-27)-12(y-27)=0
(y-12)(y-27)=0
y=12 or 27
If y=12
then x=27
If y=27
then x=12
x+y=39
xy=324
x=39-y
(39-y)y=324
39y-y^2=324
y^2-39y+324=0
y^2-27y-12y+324=0
y(y-27)-12(y-27)=0
(y-12)(y-27)=0
y=12 or 27
If y=12
then x=27
If y=27
then x=12
