Question

x+y = 6
xy = 5
what is x-y?​

Answer 1

Answer:

x-y = -4, 4

Step-by-step explanation:

x+y = 6

x = 6-y

xy = 5

x = 5/y

put the value of x = 6-y

6-y = 5/y

y(6-y) = 5

6y - y2 = 5

-y2+6y -5 = 0

-y2+5y+y-5 =0

-y(y-5) +1(y-5)

(-y+1)(y-5) = 0

y = 5

y = 1

so if y = 5 then x = 1

if y = 1 then x = 5

so x-y = 1-5 = -4

x-y = 5-1 = 4

Answer 2

Answer:

The valve of x-y= -4,4

hope this is helpfull for you.
