Find the number that must be added to each expression to form a perfect square trinomial. then write the trinomial as a binomial squared.

x^2-24x+

( )^2

Thus, when 144 is added to the given expression to form a perfect square trinomial of

Step-by-step explanation:

We are given an expression

We have find the number such that expression form a perfect square trinomial.

Using identity

Comparing the above identity with the given expression,

We get and

Thus, b = 12

and

Thus, when 144 is added to the given expression to form a perfect square trinomial of
