Question

The first two terms of the perfect square trinomial are given, find "c".

x² + 12x

A.)36
B.)144
C.)6

Answer 1

A.)36 would be the correct answer

Answer 2

A.) 36

Explanation:

For a perfect square trinomial, a = 1 b = 2x c = x². For an example, (x+3)² = x² + 6x + 9.

For this trinomial, divide "b" by 2 to get 6. Square this number and you will have 36.

x² + 12x + 36
