Question

What should be subtracted from
x2 + y2-2xy to get x2+y2 ?​

Answer 1

Answer:

x^2+y^2-2xy

use the perfect square formaula a^2 - 2ab + b^2=(a - b) ^2 where a = x and b = y

( x - y ) ^ 2

Answer 2

Answer:

$-2xy$ should be subtracted from $x^2+y^2-2xy$ to get $x^2+y^2$.

Step-by-step explanation:

Constant: A constant can be characterized as a fixed value, which is utilized in algebraic expressions and equations. A consistent doesn't change over the long haul and has a fixed value. For instance, the size of a shoe, fabric, or clothing won't change at any time.

In an algebraic equation, $x + y = 8, 8$ is a constant worth, and it remains the same.

Variables: Variables are terms that can change or differ over the long run. Its value doesn't stay consistent, in contrast to constants. For instance, an individual's level and weight don't necessarily always stay consistent, and thus they are variables.

In an algebraic equation, $x + y = 8, x$ and $y$ are the variables whose values are different and can be changed.

Let $'m'$  be the variable to be subtracted from the given equation.

$x^2+y^2-2xy+m=x^2+y^2$

Now, let separate the variable and coefficients

$m=x^2+y^2-2xy-(x^2+y^2)$

Removing the brackets

$m=x^2+y^2-2xy-x^2-y^2$

Cancelling the unlike signs

$m=-2xy$
