Trying to factor a multi variable polynomial
3.1 Factoring 4x2 + 44xy + 121y2
Try to factor this multi-variable trinomial using trial and error
Found a factorization : (2x + 11y)•(2x + 11y)
Detecting a perfect square :
3.2 4x2 +44xy +121y2 is a perfect square
It factors into (2x+11y)•(2x+11y)
which is another way of writing (2x+11y)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 :
(2x + 11y)
