What is the value of c so that x2 + 12x + c is a perfect square trinomial?
(1 point)
a. 12
b. 36
c. 72
d. 144
To determine the value of c so that x^2 + 12x + c is a perfect square trinomial, we need to find the value that completes the square. The trinomial can be factored as (x + 6)^2, so the value of c is 36.
Therefore, the correct answer is b. 36.
