According to synthetic division below, which of the following statements are true ?
Whitepunk [10]

ANSWER

C

E

F

EXPLANATION

The result of the synthetic division is :

3 -1 0

The last number is the remainder which is 0

The first two numbers are the coefficients of the quotient.

Therefore the quotient is 3x -1

Since the remainder is 0, x-4 is a factor of

f(x) = 3 {x}^{2}  - 13x +  4

This also means that:

(3 {x}^{2}  - 13x +  4)  \div (x - 4) = 3x - 1

This again means that x=4 is a root of

f(x) = 3 {x}^{2}  - 13x +  4

The correct choices are C,E and F.
