Question -

Find two numberswhose sum is 27 and product is 182.



Answer -

Let us say, first number be x andthe second number is 27 – x.

Therefore, the product of two numbers

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

Thus, either, x = -13 = 0or x – 14 = 0

 x = 13 or x = 14

Therefore, if first number = 13, then secondnumber = 27 – 13 = 14

And if first number = 14, then second number =27 – 14 = 13

Hence, the numbers are 13 and 14.
