Question

Use synthetic division to find p(-3) for p(x)=x^4-2x^3-4x+4

Answer 1

Answer:

D(-3) = x^3-5x^2+ 11, remainder 34

Step-by-step explanation:

Synthesize the equation:

0  = 1 - 2 -4 + 4

Use -3

-3 = 1 -2 - 4 + 4

Continue to synthesize: Drop the first number and multiply with the -3. Add to the next number. Keep doing this.

- 3 = 1   -2   -4   4

        |    -3   15   33

       1   -5     11   34

The last number is the remainder: 34

So D(-3) = x^3-5x^2+ 11, remainder 34

Answer 2

After using synthetic division, I found out that p(-3) for p(x)=x^4-2x^3-4x+4 is 151. I am hoping that this answer has satisfied your query about and it will be able to help you, and if you’d like, feel free to ask another question.
