What to Focus On

  • An identity is true for all values of the variables.
  • An equation may be true only for specific values.
  • Testing values helps distinguish the two.

  • Use the identity to expand a square of a binomial.
  • The identity works for positive numbers, negative numbers, and rational numbers.
  • The distributive property gives a general proof.

  • Replace b by -b in the square of sum identity to get the square of difference identity.
  • The identity is useful in finding squares of numbers near round numbers.
  • Three consecutive square numbers always give the result 2 in the stated pattern.

Common Mistakes to Avoid

An identity and an equation are the same thing.

The identity (a + b)^2 = a^2 + 2ab + b^2 works only for positive numbers or lengths.

(a + b)^2 means a^2 + b^2.
