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]

Answer:

-16

Step-by-step explanation:

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
