Now my problem is to understand the expressions 3 less than twice x You know that English is not my mother language =D .. What is less than mean !

I can't understand why you put it

(2x - 3) and (3x + 2)

what about the coordinates in the second graph !

i think by this way

we have a square piece of paper with side-length 10 cm

if we cut a small square from each corner the side lenght will be 10-2X ..... then the remaining area will be ( 10-2x )^2

what is the mistake in my way ?
