Given
- An expression having moduls function
To find
roots of the Equation
Solution
।x²-2।²+।x-2।-6 =0
Let x-2 = a____equation
then mode of a be + a
a²+a -6 =0
=>a²+3a-2a-6=0
=>a(a+3)-2(a+3) =0
=>(a+3) (a-2)=0
=>a=-3,2,0
Now putting the value of a in Equation
x-2=-3
X=-1
and
=>x-2=2
X=4
Here putting the value of -1 in actual Equation they not satisfied
Therefore value of X= (0,4)
