If t is a positive integer and r is the remainder when t^2+5t+6 is divided by 7, what is the value of r?

1) When t is divided by 7, the remainder is 6
2) When t^2 is divided by 7, the remainder is 1

From first condition :

Let t = 7m + 6

Then t^2 + 5t + 6
= (7m+6)^2 + 5(7m+6) + 6
=49m^2 + 119m + 72
=7(7m^2+17m +10) +2

Hence r = 2

2nd condition does not provide what is r, as t will come in square root form
