Answer 2

The value of (x²-y²) will be "15$\sqrt{161}$". Further explanation is given below.

Step-by-step explanation:

Given values is

x+y=15 and xy=16

Then,

(x-y)²=(x+y)²-4xy

On putting the values of (x+y) and (xy) in the above formula, we get

⇒ (x-y)²= (15)²-4×16

⇒         = 15×15-4×16

⇒         = 225-64

⇒ (x-y)²= 161

⇒  (x-y) = $\sqrt{161}$

As we know,

(x²-y²)= (x+y) (x-y)

On putting the values of (x+y) and (x-y) in the above formula, we get

⇒ (x²-y²)= (15) ($\sqrt{161}$)

⇒           = 15$\sqrt{161}$
