Question

The remainder when f(x) =4x³-3x²+2x-1 is divided by 2x+1 is

Answer 1

Answer:

-13/4

Step-by-step explanation:

let f(x) be divided by g(x)

here g(x)=2x+1

2x+1=0

x=-1/2

now according to the remainder theorem

f(x)=4×(-1/2)^3-3×(-1/2)^2+2×-1/2-1

=4×-1/8-3×1/4+-1-1

=-1/2-3/4-2

=-5/4-2

=-13/4
