Question

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

Answer 1

Answer: 144

Step-by-step explanation: To find a value of c that would make this a perfect square, take -24 and divide it by 2 to get -12. Next, simply square -12 to get 144.

x^2 - 24x + 144 can be factored into (x - 12)(x - 12)

Answer 2

Answer:

144 is the correct answer
