Answer:
First blank has the value r.
Second blank has the value 2
Step-by-step explanation:
The given equation on the left side is [tex]( r- s)^{2}[/tex]
Now, ALGEBRAIC IDENTITY states that
[tex]( a- b)^{2}[/tex] = [tex]a^{2} + b^{2} - 2 \times a \times b[/tex]
Here, comparing a = r and b = s, we get
[tex]( r- s)^{2}[/tex] = [tex]r^{2} + s^{2} - 2 \times r \times s[/tex]
So, the first blank has the value r.
Second blank has the value 2
