Explanation:
we have
now we have two cases
- Case 1(
(x+45)>=0;x>=-45 ........(a)
(x+45)=-6
x=-6-45; x=-51 .........(b)
from (a) and (b) we get
x in phi - Case 2(
(x+45)<0;x<-45 ......(d)
-(x+45)=-6 ........(a negative sign is there because for any value of x<-45,(|A|), A will be negative)
now we getx=-39 ..............(e)
Again from (d)and (e)
x in phi
hence there is no real solution for x
i.e.x in phi
