ANSWER:✏️
solving perfect square of trinomials
1. x² + 25x + 16
a² = x² b² = 16
a = x b = 4
2ab = 2•(x)•(4)
=8x
Not perfect square trinomial
factor: (x + 4) (x + 4)
________________________________
2. x² + 36x + 49
a² = x² b² = 49
a = x b = 7
2ab = 2•(x) • (7)
= 14
Not perfect square trinomial
factor: (x+7) (x+7)
________________________________
3. 4x² + 16x + 81
a² = 4x² b² = 81
a = 2 b = 9
2ab= 2•(2x)•(9)
=36
Not perfect square trinomial
factor: (2x + 9) (2x +9)
hindi po ako sure sa answer ko
pero na recall na po kase samin yan
