Answer:
-16
Step-by-step explanation:
As we have
[tex] {x}^{2} - {y}^{2} = (x + y)(x - y)[/tex]
Here
x= -3
y= -5
Subtitute x and y
[tex] {x}^{2} - {y}^{2} \\ ( - 3{)}^{2} - ( - 5 {)}^{2} \\ 9 - 25 \\ - 16[/tex]
We first need to substitute
Since x = -3 and y = -5
(-3+-5)(-3 - -5)
Let's Solve (-3+-5)
which = -8
Then Solve (-3 - -5)
which = 2
Now -8 × 2 = -16
Hence, Answer = -16
