Question

(x+y)(x–y), if x=−3, y=−5

Answer 1

Answer: answer is -16

Step-by-step explanation:

Substitute the values of x and y into the equation to give

(3 + (-5)) (3-(-5))

(3-5) (3+5)

(-2) (8)

-16

Answer 2

First, you apply the numbers into the problem. (-3 + (-5) (-3 - (-5). Then, you solve. (-3 + (-5) is equal to (-3 - 5), so the answer for that would be -8. (-3 - (-5) is equal to (-3 + 5), which is 2. Now, you multiply -8 and 2. So your answer would be -16. I hope this helps :)
