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.
