3*5^2+5*5-7 = 93 which will be the remainder you'll get if you do the synthetic division.

Let f(t) = 3t^2 + 5t -7 ......................i
Since we have to divide by (t-5)
Therefore put t -5 =0
or t=5
Put t=5 in i
f(5) = 3(5)^2 + 5(5) -7
= 75 +25 -7
= 93
Hence the remainder is 93

Plug t=5 into your polynomial. The remainder theorem says that this will be the remainder if you had divided.

The remainder is: 93/(t-5) not 93!
