Ответ:
x2 - x + 1/4 becomes (x-1/2)2
it becomes perfect square so the correct answer for the above is
B that is 1/4
hope it helps
Ответ:
The correct option is (b)
Step-by-step explanation: We are given to select the correct constant that can added to , so thet it becomes a perfect square trinomial.
A perfect square trinomial is of the following form:
Let the constant to be added be 'b'. Then, we can write
So, for the given expression to be perfect trinomial,
Thus, (b) is the correct option.
