Concept:The Remainder Theorem states that when a polynomial f(x) is divided by (x−c), the remainder is f(c).Explanation:Let f(x)=2x3−11x2+8x−1.The divisor is x+3.Set x+3=0, so x=−3.Substitute x=−3 into f(x):f(−3)=2(−3)3−11(−3)2+8(−3)−1Simplify each term:2(−27)−11(9)−24−1=−54−99−24−1=−178Answer:The remainder is −178, which is option D.
