Answer 1

To form a perfect square trinomial, you need to add a constant term that is half the coefficient of the middle term squared.

Step-by-step explanation:

In order to form a perfect square trinomial, we need to add a constant term that is half the coefficient of the middle term squared. In the expression x²+4x+3, the coefficient of the middle term is 4. Half of 4 is 2, and 2 squared is 4. So we need to add 4 to the expression to form a perfect square trinomial.
