Pulling out like terms
4.1 Pull out like factors :
8x2 + 24xy + 18y2 = 2 • (4x2 + 12xy + 9y2)
Trying to factor a multi variable polynomial :
4.2 Factoring 4x2 + 12xy + 9y2
Try to factor this multi-variable trinomial using trial and error
Found a factorization : (2x + 3y)•(2x + 3y)
Detecting a perfect square :
4.3 4x2 +12xy +9y2 is a perfect square
It factors into (2x+3y)•(2x+3y)
which is another way of writing (2x+3y)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 + 3y)2
