Question

If the sum of two numbers is 25 and their multiplication is 100, then
find their difference,​

Answer 1

Answer:

Step-by-step explanation:

Let the numbers be x,y

Given x+y=25

x*y=100

x=100/y

100+y^2=25y

y^2-20y-5y-100=0

y(y-20)-5(y-20)=0

y=5 and y=20

If y=5 then x=20

If y=20 then x=5

x-y=15 or -15
