Perfect square trinomial:
A perfect square trinomial has the following format:

a.
x² – 8x

So 2a = 8, a = 4. Then

The perfect square trinomial is 
b. x2 + 20x +
2a = 20, so a = 10

The perfect square trinomial is 
C.
x² – 16x +
2a = -16, so a = -8.

The perfect square trinomial is 
d. x2 + 9x +
, so 

The perfect square trinomial is
