Answer 1

Answer:

चले आओ ना अब,

कहाँ गुम हो?

कितनी बार कहूँ?

मेरे दर्द की दवा तुम हो

Answer 2

STEP BY STEP SOLUTION:

p(t) = 2+t+2t²-t³

Putting t = 0

p(0) = 2 + 0 + 2(0)²-(0)³

= 2+0+0 -0

= 2

Putting t = 1

p(1) = 2 + 1+ 2(1)²-(1)³

= 2+1+2-1

= 4

Putting t = 2

p(2)=2+2+2(2)²-(2)³

= 2+2+2(4)-8

= 2+2+8-8

=4
