You must solve for 2 cases:
one for a positive expression inside the absolute value
and another for a negative expression inside the absolute value sign
..
case 1:
-2p≤1
-p≤1/2
mult.both sides by (-1) and reverse inequality sign
p≥-1/2
..
case 2:
-(-2p)≤1
2p≤1
p≤1/2
solution:
[-1/2,1/2]
or
-1/2 ≤ p ≤1/2
