Hello MHB,

I am solving some old exam and I am stuck at one problem

it says 'outline the following two amounts'

If we start with number 1.

we know for the part \(\displaystyle (x-1)(x-5)\leq0\) x has to be \(\displaystyle 1\leq x \leq 5\)

part number 2.

\(\displaystyle (x-3)(x-4)>0\) we know that \(\displaystyle x>4\)

part number 3.

\(\displaystyle (x-2)(x-6)\leq0\) we have\(\displaystyle 2\leq x\leq6\)

for number 1 and 2 we got

\(\displaystyle 4 < x \leq 5\)

and part 2 and 3 we got:

\(\displaystyle 4<x \leq 6\)

Is this correct?

Regards,

\(\displaystyle |\rangle\)
