Question

Which value must be added to the expression x^2– 3x to make it a perfect-square trinomial?

Answer 1

Answer:

$\frac{9}{4}$

Step-by-step explanation:

Given

x² - 3x

add ( half the coefficient of the x- term)²

x² + 2(- $\frac{3}{2}$)x + (- $\frac{3}{2}$)²

= (x - $\frac{3}{2}$)² + $\frac{9}{4}$
