Question

Find the remainder when f(x) = 2x3 – 12x2 + 11x + 2 is divided by x – 5.
Answer:
A) 3
B) –7
C) 7
D) –3

Answer 1

The remainder of the function divided by a factor can be obtained by substituting the factor to the function. In this case, we substitute 5 to the x in the expression 2x3 – 12x2 + 11x + 2. The answer is equal to 7. The answer hence to this problem is C 

Answer 2

The remainder when the function is divided by (x – 5) is 3. Then the correct option is A.

What is the remainder?

The remainder when f(x) = 2x3 – 12x2 + 11x + 2 is divided by x – 5 will be

        2x² – 2x + 1            

x – 5) 2x³ – 12x² + 11x – 2

          2x³ – 10x²                  

           00  –2x² + 11x

                     –2x² + 10x        

                        00 + x – 2

                                 x – 5

                                 0 + 3

Then the correct option is A.
