Question

Use synthetic division and the remainder theorem to find P(–1) if P(x) = 2x3+3x2-x–3.

Answer 1

Answer:

The value of P(-1) is -1

∴ P(-1)=-1

Step-by-step explanation:

Given polynomial is $P(x)=2x3+3x2-x-3$

To solve the given polynomial by using synthetic division and the remainder theorem to find P(–1):

By using the Synthetic division and remainder theorem we can solve it.

From the given P(-1) we can write it as

-1_|  2      3     -1    -3

      0     -2     -1     2

  _________________

      2       1      -2    -1

Hence we get the remainder -1

The value of P(-1) is -1

∴ P(-1)=-1
