Answer:
One no. is 8 and other is 6.
Step-by-step explanation:
Let the numbers be x and y
Given that
xy = 48 Equation 1
x+y = 14 Equation 2
Since,
x+y = 14
On both side squaring.
(x+y)² = 14²
x² + y²+2xy = 196
x² + y² + 2×48 = 196
x² + y² + 96 = 196
x² + y² = 100
( x-y)² +2xy = 100
( x-y)² +2×48 = 100
( x-y)² +96 = 100
(x-y)² = 4
x-y = √4
x-y = 2 Equation 3
Add equation 2 and 3
x+y+x-y = 16
2x = 16
x = 8
Substitute the value of x in the equation 2
x+y = 14
8+y = 14
y = 14-8
y= 6
Hence, the numbers are 8 and 6.
