STEP1:Trying to factor a multi variable polynomial
1.1 Factoring r2 - 2rs + s2
Try to factor this multi-variable trinomial using trial and error
Found a factorization : (r - s)•(r - s)
Detecting a perfect square :
1.2 r2 -2rs +s2 is a perfect square
It factors into (r-s)•(r-s)
which is another way of writing (r-s)2
How to recognize a perfect square trinomial:
• It has three terms
• Two of its terms are perfect squares themselves
• The remaining term is twice the product of the square roots of the other two terms
Final result :
(r - s)2
