4.2 Factoring 4x2 + 20xy + 25y2
Try to factor this multi-variable trinomial using trial and error
Found a factorization : (2x + 5y)•(2x + 5y)
Detecting a perfect square :
4.3 4x2 +20xy +25y2 is a perfect square
It factors into (2x+5y)•(2x+5y)
which is another way of writing (2x+5y)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 :
2 • (2x + 5y)2
