We have,
Let the two number is x and y.
So,
x+y=12......(1)
Now, According to given question,
xy=32
y=32x......(2)
From equation ( 1) and ( 2) to, and we get,
x+32x=12
⇒x2+32=12x
⇒x2−12x+32=0
⇒x2−(8+4)x+32=0
⇒x2−8x−4x+32=0
⇒x(x−8)−4(x−8)=0
⇒(x−8)(x−4)=0
If, x−8=0,x=8
If,x−4=0,x=4
So,
From ( 1) to,
x+y=12
⇒8+y=12
⇒y=4
Hence, the number is 8and4.
