find two numbers whose sum is 27 and product is 182
Answers
Let the first number be x and the second number is 27 - x.
Therefore, their product = x (27 - x)
It is given that the product of these numbers is 182.
Therefore,
x(27 - x) = 182
⇒ x2 – 27x + 182 = 0
⇒ x2 – 13x - 14x + 182 = 0
⇒ x(x - 13) -14(x - 13) = 0
⇒ (x - 13)(x -14) = 0
Either
x = -13 = 0 or x - 14 = 0
⇒ x = 13 or x = 14
If first number = 13,
then
Other number = 27 - 13 = 14
If first number = 14,
then
Other number = 27 - 14 = 13
Therefore, the numbers are 13 and 14.
Here you Go.
____________________
• Let the first no. be "a"
• Then the second no. = (27 - a)
Product = 182
• a(27 - a) = 182
• 27a - a² = 182
• a² - 27a + 182 = 0
• a² - 14a - 13a + 182 = 0
• a(a - 14) - 13(a - 14) = 0
• (a - 14)(a - 13) = 0
When (a - 14) = 0
----> a = 14
----> 27 - a = 13
When (a - 13) = 0
----> a = 13
----> 27 - a = 14
