Use Synthetic Division f(x) by x−k for the given value of k. Then express f(x) in the form f(x)=(x−k)q(x)+rf ( x ) \text { by } x - k \text { for the given value of } k \text {. Then express } f ( x ) \text { in the form } f ( x ) = ( x - k ) q ( x ) + r

Question 109

Multiple Choice

Use synthetic division f(x)  by x−k for the given value of k. Then express f(x)  in the form f(x) =(x−k) q(x) +rf ( x ) \text { by } x - k \text { for the given value of } k \text {. Then express } f ( x ) \text { in the form } f ( x ) = ( x - k ) q ( x ) + r for the given value of k.
- f(x) =−6x3+2x2+5x−10;k=2f ( x ) = - 6 x ^ { 3 } + 2 x ^ { 2 } + 5 x - 10 ; \quad k = 2


A) f(x) =(x+2) (−6x2+10x+25) −40f ( x ) = ( x + 2 ) \left( - 6 x ^ { 2 } + 10 x + 25 \right) - 40
B) f(x) =(x−2) (−6x2−10x+15) −40f ( x ) = ( x - 2 ) \left( - 6 x ^ { 2 } - 10 x + 15 \right) - 40
C) f(x) =(x−2) (−6x2+10x+25) −40f ( x ) = ( x - 2 ) \left( - 6 x ^ { 2 } + 10 x + 25 \right) - 40
D) f(x) =(x−2) (−6x2−10x−15) −40f ( x ) = ( x - 2 ) \left( - 6 x ^ { 2 } - 10 x - 15 \right) - 40
