Question

if x²-y² =- 24 and (x+y)=8 then (x-y) is what ​

Answer 1

Answer:

-32

Step-by-step explanation:

property says  (x+y)(x-y)= x²-y²

So 8+(x-y)= -24

x-y= -24-8

(x-y) = -32

Answer 2

x² - y² = - 24

Using the identity

• x² - y² = ( x + y ) ( x - y )

Given ( x + y ) = 8

8 ( x - y ) = - 24

( x - y ) = 24/8

( x - y ) = 3 ➡ Answer
