Answer 2

Answer:

The algebraic identity $(x - y)^{3}$ can be expressed as $(x - y)^{3} = x^{3} -3x^{2} y +3y^{2} x -y^{2}$

Step-by-step explanation:

The given algebraic expression is $(x - y)^{3}$. An algebraic expression is a polynomial that contains variables and constants, x and y are variables.

We need to evaluate the formula $(x - y)^{3}$.

where x and y are variables and we need to evaluate the cube of their differences.

So, the expression $(x - y)^{3}$ is actually an algebraic expression and also happens to be an algebraic identity,

There are more algebraic expressions other than this, such as $(a-b)^{2}= a^{2} -2ab+b^{2}$  $(a+b)^{2}= a^{2} +2ab+b^{2}$ many more.

So, we express $(x - y)^{3}$ as ;

$(x - y)^{3} = x^{3} -y^{3} -3xy(x-y)$

Which can be further simplified as,

$(x - y)^{3} = x^{3} -y^{3} -3x^{2} y + 3xy^{2} = x^{3} -3x^{2} y +3y^{2} x -y^{2}$

So, finally,

$(x - y)^{3} = x^{3} -3x^{2} y +3y^{2} x -y^{2}$

Therefore, the algebraic identity $(x - y)^{3}$ can be expressed as $(x - y)^{3} = x^{3} -3x^{2} y +3y^{2} x -y^{2}$

There are more algebraic expressions other than this, such as $(a-b)^{2}= a^{2} -2ab+b^{2}$  $(a+b)^{2}= a^{2} +2ab+b^{2}$ many more.
