and the ms office version

thanks astar...i've got another question it's from the may/june 03 paper...|x-2|less than 3-2x..my question is do i have to square both sides?

loggerhead:
no you don't but you can.

the way i like to do it is find the CV's by solving the equations:

x - 2 = 3 - 2x         and        x - 2 = - 3 + 2x


both this method and squaring give the same CV's but this way is faster as there is no quadratic.

astarmathsandphysics:
You are correct. I also prefer this way.
