Using the Factors (5x+2)( - 5 x + 2 ) And (x1)( x - 1 )

Question 108

Multiple Choice

Using the factors (5x+2) ( - 5 x + 2 ) and (x1) ( x - 1 ) , find the remaining factor(s) of f(x) =10x4+31x384x2+53x10f ( x ) = 10 x ^ { 4 } + 31 x ^ { 3 } - 84 x ^ { 2 } + 53 x - 10 and write the polynomial in fully factored form.


A) f(x) =(5x+2) (5x+2) (2x1) (x1) f ( x ) = ( - 5 x + 2 ) ( - 5 x + 2 ) ( 2 x - 1 ) ( x - 1 )
B) f(x) =(5x+2) (x5) (2x1) (x1) f ( x ) = ( - 5 x + 2 ) ( - x - 5 ) ( 2 x - 1 ) ( x - 1 )
C) f(x) =(5x+2) 2(2x1) (x+1) f ( x ) = ( - 5 x + 2 ) ^ { 2 } ( 2 x - 1 ) ( x + 1 )
D) f(x) =(5x+2) (x+5) 2(x+1) f ( x ) = ( - 5 x + 2 ) ( - x + 5 ) ^ { 2 } ( x + 1 )
E) f(x) =(5x+2) 2(x1) 2f ( x ) = ( - 5 x + 2 ) ^ { 2 } ( x - 1 ) ^ { 2 }
