Question 67

Multiple Choice

Find all rational zeros and factor f(x) .
- f(x) =10x3+53x2+14x5f ( x ) = 10 x ^ { 3 } + 53 x ^ { 2 } + 14 x - 5


A) 110,1,5;f(x) =(10x+1) (x1) (x+5) - \frac { 1 } { 10 } , 1 , - 5 ; f ( x ) = ( 10 x + 1 ) ( x - 1 ) ( x + 5 )
B) 2,5,5;f(x) =(x+2) (x5) (x+5) - 2,5 , - 5 ; f ( x ) = ( x + 2 ) ( x - 5 ) ( x + 5 )
C) 12,15,5;f(x) =(2x+1) (5x1) (x+5) - \frac { 1 } { 2 } , \frac { 1 } { 5 } , - 5 ; f ( x ) = ( 2 x + 1 ) ( 5 x - 1 ) ( x + 5 )
D) 2,5,5;f(x) =(2x+1) (5x1) (x+5) - 2,5 , - 5 ; f ( x ) = ( 2 x + 1 ) ( 5 x - 1 ) ( x + 5 )
