Let the number be x and y
so,
x × y = 24.......1st equation
and,
x + y = 14
x = 14 - y .......2nd eqn
than,
( 14 - y) y = 24
14y - y² = 24
y²- 14y + 24 = 0
y² - 12y - 2y + 24 = 0
y( y - 12) - 2( y - 12) = 0
( y - 2) ( y - 12) = 0
y = 2 , 12
and ,
put value of y in 1st or 2nd eqn to find x

One number is 12 and the other is 2.
Given:
Product of two numbers = 24
Sum of two numbers = 14
To Find:
The two numbers
Solution:
Let the two numbers be x and y
Therefore, according to the question,
From equation (ii)
Put the value of y in equation (i)
Now, put the value of x in the equation (i):
if x = 12 ; y = 24/12 = 2
fi x = 2 ; y = 24/2 = 12
Therefore one number is 12 and the other is 2.
