Question

If x²+y²=73 and xy=24 then x+y is equal to​

Answer 1

Answer:

As we know that

(x+y)

2

−(x−y)

2

=4xy

putting the value of (x-y) and xy , we get

(x+y)

2

−(2)

2

=4×24

⇒(x+y)

2

=4+4×24

⇒(x+y)

2

=100

∴(x+y)=10or−10

Since x and y are positive, we take

(x+y)=10

Now,

x

+

y

=

xy

x+y

=
