Which of the following constants can be added to x^2+2/3 to form a perfect square trinomial? 1/9 4/9 4 1/9

As your question is stated, there is no answer!

I'm going to assume the polynomial you meant is:

To create a perfect square trinomial, take half the coefficient of x and then square it.

In all problems like this, you want to square half the coefficient of x -- always half.

answer: 140

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people
