Notes 8.4 – MULTIPLYING SPECIAL CASES

I. Perfect Square Binomials Simplify the following expressions: 1.) 2.) 3.) Notice anything special about the middle term?

The Square of a Binomial The of a binomial is the SQUARE of the FIRST term plus the PRODUCT of the terms plus the SQUARE of the LAST term. SQUARE TWICE

Example: Simplify the expression:
