Find two whole numbers whose sum is 27and product is 182
Answers
Given:
The sum of two numbers is 27.
The product of two numbers is 182.
Find:
The numbers
Solution:
Let the one number be 'x'
Let the another number be 'y'.
The sum of two numbers is 27.
One number + other number = 27
=> x + y = 27
=> x = 27 - y ........(i)
The product of of two numbers is 182.
One number other number = 182
=> x × y = 182 .....(ii).
Putting the value of 'x' from equation (i) in equation (ii)
=> x × y = 182
=> (27 - y)y = 182
=> 27y - y² = 182
=> y² - 27y + 182 = 0
=> y² - 14y - 13y + 182 = 0
=> y(y - 14) - 13(y - 14) = 0
=> (y - 13) (y - 14) = 0
=> y = 13 or y = 14
Putting the value of 'y' in equation (i)
y = 13
=> x = 27 - y
=> x = 27 - 13
=> x = 14
y= 14
=> x = 27 - y
=> x = 27 - 14
=> x = 13
Hence, the two numbers are 13 and 14.
I hope it will help you.

Answer:
=> x × y = 182
=> (27 - y)y = 182
=> 27y - y² = 182
=> y² - 27y + 182 = 0
=> y² - 14y - 13y + 182 = 0
=> y(y - 14) - 13(y - 14) = 0
=> (y - 13) (y - 14) = 0
=> y = 13 or y = 14
