Question

Complete the following: (r-s)^2 = (___)^2 -(___)rs + s^2

Answer 1

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 $( r- s)^{2}$

Now, ALGEBRAIC IDENTITY states that

$( a- b)^{2}$ = $a^{2} + b^{2} - 2 \times a \times b$

Here, comparing a = r and b = s, we get

$( r- s)^{2}$ = $r^{2} + s^{2} - 2 \times r \times s$

So, the first blank has the value r.

Second blank has the value 2
