Kristina used synthetic division to divide the polynomial f(x) by x−2, as shown on the table. What is the value of f(2)? −14 −11 −2 −1 A synthetic division setup with respective columns containing the following numbers column 1 containing two as a divisor, column 2 containing negative 1, blank and negative 1, column 3 containing negative 5, negative 2, negative 7, and column 4 containing three, negative 14, negative 11.There is a line above the numbers negative 1, negative 7 and negative 11.
Question
Answer:
Answer:-11Step-by-step explanation:The answer to the first one sould be -11 2x^3 +5x^2−x−6 Write 5x^2 as 4x^2 + x^2......and we have..... 2x^3 + 4x^2 + x^2 - x - 62x^2 ( x + 2) + ( x + 2)(x - 3)(x + 2) [ 2x^2 + x - 3](x + 2) (2x +3) (x - 1) x^3−4x^2−3x+18 = 0Using some synthetic division, we have 3 [ 1 - 4 -3 18 ] 3 -3 -18 _______________ 1 -1 -6 0 The remaining polynomial is x^2 - x - 6 which factors as (x - 3) ( x + 2) So .... the factored form is (x - 3) ( x - 3) ( x + 2) = ( x + 2) ( x - 3)^2 = 0
