Which of the following are identities? I. y=x II. 4=3x2+2 III. x=x−−√ A. II and III B. I and III C. all D. none

Respuesta :

None of the expressions is an identity

How to determine the identities?

The expressions are given as:

I. y=x

II. 4 = 3x^2 + 2

III. x=x

In algebra, there are three identities; and they are

  • (x+y)^2 = x^2 + y^2 + 2xy
  • (x-y)^2 = x^2 + y^2 – 2xy
  • x^2 – y^2 = (x+y) (x-y)

None of the given expression take the above forms

Hence, none of the expressions is an identity
