Question

What value of c makes x2 − 24x + c a perfect square trinomial? −144 −48 48 144

Answer 1

I believe that the answer is 144 

Answer 2

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.
