Find two numbers whose sum is 27 and product is 182.


Q3: Find two numbers whose sum is 27 and product is 182.

Answer:
Let the first number  = x
Given that sum is 27
 Then  second number is = 27 –   x
Given that product is 182.
So that
      x(27 –   x) = 182
    27  x –    x2 – 182 = 0
      x2 – 27  x + 182 = 0
    now factorize it we get

Thus the two numbers are 13 and 14
