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

144

Step-by-step explanation:

Perfect square formula: a^2 - 2ab + b^2 (because that equals (a-b)^2)

x^2-2*12x+c

a = 1

b = 12

12^2 = 144

The value of makes perfect square.

Step-by-step explanation:

We have to make

Since, Perfect square formula:

Re-write as,

Compare above with

Where a = x  and b= 12

so,

⇒

Hence,

Therefore, the value of makes perfect square.

where r the answers
