Question

Use the remainder theorem to determine the remainder when 3t2 + 5t − 7 is divided by t − 5. A. 93 B. 43 C. 107 D. 57

Answer 1

Using remainder theorem, we get:

$P(t) = 3t^{2} + 5t - 7$

Substitute t = 5 into the equation:
$P(5) = 3(5)^{2} + 5^{2} - 7$
$P(5) = 75 + 25 - 7 = 93$

Thus, we get a remainder of 93 or (A)

Answer 2

The answer for your question is A. 93
