@sumit1234567890 how please explain
ur eqn a^2 +1 + 2a = (a+1)^2 = 0

a=-1

hence 0
5210
@charvar said:
@sumit1234567890 how please explain
this is the formula of (a+1)^2=0
a+1=0
a=-1
now put the values to get the result
5211
@Brooklyn (-1)^37=-1
(-1)^100=1
-1-1=-2

Charvar bhai, question mein typo tha ..isley samjh nahi aa raha tha ki kaise karein.. :)
otherwise it was a pure simple quadratic equation and can be solve by using simple value subsitition.
