Question

What is the value of the expression (x – y)2 when x = 5 and y = -1

A. 36
B. 16
C. 4
D. 24

Answer 1

36

Explanation:

You are given an expression and values to be put into it.

Simply substitute the values in instead of
`x` and
`y`.

`(x-y)^2`

When
`x=5` and
`y=-1`:

`(5-(-1))^2 = (5+1)^2=(6)^2=36` - Note: Be careful with negative signs here. Two negatives make a positive.
