All you have to do is plug the values into the equation.
(5 - (-1))^2 = 6^2 = 36.
The value of the expression (x-y)² when x = 5 and y = -1 is 36
From the question, the given expression is (x-y)^2
First, we will write this expression properly,
The expression, written properly is (x-y)²
Now, to determine the value of the given expression [(x-y)²] when x = 5 and y = -1,
We will put the given values of the variables (x and y) into the expression and simplify.
The given expression is
(x-y)²
Now, put the given respective values of x and y into the equation,
That is, put x = 5 and y = -1
Then,
(x-y)² = (5--1)²
= (5+1)²
(NOTE: -- = +)
= 6²
= 36
Hence, the value of the expression (x-y)² when x = 5 and y = -1 is 36
