Answer:
4,8
Step-by-step explanation:
(i)
Let one number = x.
Then the other number = 12 - x.
(ii)
Given that product is 32.
⇒ x * (12 - x) = 32
⇒ 12x - x² = 32
⇒ 12x - x² - 32 = 0
⇒ -x² + 12x - 32 = 0
⇒ x² - 12x + 32 = 0
⇒ x² - 8y - 4y + 32 = 0
⇒ x(x - 8) - 4(x - 8) = 0
⇒ (x - 4)(x - 8) = 0
⇒ x = 4,8.
When x = 4:
⇒ 12 - x
⇒ 12 - 4
⇒ 8.
When x = 8:
⇒ 12 - 8
⇒ 4.
Therefore, the numbers are 4 and 8.
Hope it helps!
