1057use wavy-curve method...
The inequation is (2x + 3) ( x - 1) / ( x - 2) ≤ 0
The critical points are -3/2 , 1 ,2 .
I know how to locate them on the number line and I also know how to write the signs.
But I don't know how to go about in writing the solution after writing the number line.
Please answer.

1The teacher had taught the method.
I forgot.
He didn't use any wave which connects all the points located on the number line.
I saw that the wave should be joined in the net.
But he had taught in another method which I have forgotten.
I have told all that I have done.
But not sure of how to write the solution.
