Use the remainder theorem to determine the remainder when 3t²+5t-7 is divided by t-5
a.93
b.57
c.43
d.107

which means the remainder upon dividing by is 93.

This is because we can write



where is the quotient and is the remainder. Multiplying both sides by , then evaluating at makes the term vanish, leaving the remainder:

Im pretty sure it would be 6 purple rectangles.
