B^2 - 4ac
(-9)^2 - 4 (2)(9)
= 81 - 72
=9 >0 yet it is a perfect square (3^2 =9)
So , it is 2 real and rational roots
(x-3) ( 2x-3) =0
x = 3 , x = 3/2

Answer:
The graph in the attached figure
Step-by-step explanation:
we have

The solution of the inequality is the shaded area above the dashed line 
The slope of the dashed line is negative m=-1
The y-intercept of the dashed line is (0,2)
The x-intercept of the dashed line is (2,0)
To graph the inequality, plot the intercepts, draw the dashed line and shading the area above the dashed line
