Answer:
Option D. 144
Step-by-step explanation:
The given trinomial is x² - 24x + c and we have to find the value of c for which the given trinomial is a perfect square trinomial.
Out of given options for the value of c = 144 the given trinomial becomes as
x² - 24x + 144 = (x - 12)² which is a perfect square.
Therefore for c = 144 trinomial is a perfect square.
Option d. 144 is the correct option.
