Perfect Trinomial Square    Factoring      Fun Help     Game Tips:

- Perfect squares are formed by multiplying a quantity times itself, as in (3)(3) =9 .
   Here are six perfect squares: 16,  25,  (-6)2,  r2,  (y+3)2,   (2w-5t)2 .

- A 'Perfect Trinomial Square' is the square of a binomial.
   For example, the perfect trinomial a2+2ab+b2 can be formed from (a+b)2.
   This means a2+2ab+b2 can be factored as (a+b)(a+b).

- Similarly, the 'Perfect Trinomial Square'  a2-2ab+b2  can be factored into the two factors (a-b)(a-b).
   If you check (a-b)(a-b) , it multiplies together to give you the perfect trinomial a2-2ab+b2.
