Question

If x-y=2 and xy=24,what is the value of x+y?​

Answer 1

Answer:

x-y=2

(x-y)²=4

(x+y)²-4xy=4

(x+y)²-4.24=4

(x+y)²=100

x+y=10

Answer 2

Answer:

x+y=(+/-) 10

Step-by-step explanation:

x-y=2 and xy=24

as we know that

(x-y)^2=x^2+y^2-2xy

from here

x^2+y^2=52

(x+y)^2=x^2+y^2+2xy

putting the value of x^2+y^2=52 and xy=24

(x+y)^2=52+48=100

then x+y=(+/-) 10
