Answer:
2 & 8
-4 & -4
Step-by-step explanation:
x and y are the numbers, as per question:
x= 4+2y and xy= 16
- y(4+2y)= 16
- 2y²+4y=16
- y²+2y - 8= 0
- y²+2y+1 =9
- (y+1)²=9
- y+1=3 ⇒ y= 2 ⇒ x= 4+2*2= 8
- y+1= -3 ⇒ y= -4 ⇒ x= 4+2*(-4)= -4
5+4=9 therefore the number is divisible by 9.
9×6=54
Then you find the prime factors of the two numbers that times together to make 54.
9=3×3
6=3×2
So 2×3×3×3=54
OR 2×3^3
