What to Focus On

  • An identity is true for every value of the variable.
  • Checking a few values can help confirm an identity.
  • If both sides always give the same result, the equation is an identity.

  • There are four special products of two binomials.
  • The sign pattern is very important.
  • The coefficient of x comes from adding or subtracting the two constants.

  • The product of a sum and a difference removes the middle term.
  • It gives the difference of squares.
  • It is useful for fast calculation.

Common Mistakes to Avoid

An identity is just any equation with variables.

In (a + b)^2, the middle term is b^2 or a^2 instead of 2ab.

In (a - b)^2, the middle term is positive because squaring removes the minus sign.
