Final answer:

To make the expression x² + x a perfect-square trinomial, we add the square of half the coefficient of the x term.


Step-by-step explanation:

To make the expression x² + x a perfect-square trinomial, we must add the square of half the coefficient of the x term. In this case, the coefficient of x is 1, so we add (1/2)² = 1/4 to the expression. Therefore, the expression becomes x² + x + 1/4, which is a perfect-square trinomial.
