The answer is just 3 only because if you plug in 3 to subsitute

Answer:

 Roots of the equation x² - 6x + 9 = 0 are 3,3 .

Step-by-step explanation:

As given the expression in the question be as follow.

x² - 6x + 9 = 0

Simplify the above equation

x² - 3x - 3x + 9 = 0

x (x - 3) - 3 (x -3) = 0

(x - 3)( x - 3) = 0

x = 3, 3

Therefore the  roots of the equation x² - 6x + 9 = 0 are 3,3 .
