Fix and PROVE the conjecture x c iff x c or x c by starti

Fix and PROVE the conjecture |x| = c iff x = c or x = -c

by starting with “|x| = c iff\"

Solution

1. |x| means absolute value of x

when x is - ve |x| will take only te value of the quantity and not the sign

ie when x= c , |x| =c and when x= -c also |x| = c

2 .. when |x| =c means the quantity is c or -c for both the values |x| =c

2 .
