Respuesta :

Answer: neither A or B

Step-by-step explanation:

Both (A) and (B) are not true identities.

What is an equation?

  • An equation is a formula in mathematics that expresses the equality of two expressions by connecting them with the equals sign =.

What is an identity?

  • An identity in mathematics is equality that connects one mathematical expression A to another, such that A and B (which may contain some variables) yield the same value for all values of the variables within a certain range of validity.

Identity equations:

  • [tex](x+y)^{2} =x^{2} +2xy+y^{2}[/tex]
  • [tex](x-y)^{2} =x^{2} -2xy+y^{2}[/tex]
  • [tex](x+y)^{3} = x^{3} +y^{3} +3ab(a+b)[/tex]
  • [tex](x-y)^{3} =x^{3} -y^{3} -3ab(a-b)[/tex]
  • [tex](x+y)^{4} =x^{4} +4x^{3} y+6x^{2} y^{2} +4xy^{3}+y^{4}[/tex]
  • [tex](x-y)^{4} = x^{4} -4x^{3} y+6x^{2} y^{2} -4xy^{3} +y^{4}[/tex]

Therefore, both (A) and (B) are not true identities.
