Let first number be x
Let the second number be 39-x
According to the question,
(x) (39-x) =324
39x-x²=324
-x²+39x-324=0
-(x²-39x+324)
x²-39x+324=0
Now splitting the middle term
x²-27x+12x+324=0
x(x-27)+12(x-27)
x=27 or x=-12
Let the second number be 39-x
According to the question,

-(x²-39x+324)
x²-39x+324=0
Now splitting the middle term
x²-27x+12x+324=0
x(x-27)+12(x-27)
x=27 or x=-12
