Question

4x³-3x²+5x+4divided by 2x+1 using remainder theorem

Answer 1

Answer:

Step-by-step explanation:

p[x]= 4x³-3x²+5x+4

g{x}=2x+1

if g[x]=0

2x+1=0

x=-1/2

P[1/2]= 4×[-1/2]³-3×[-1/2]²+5×[-1/2]+4

       =4×[-1/8]-3×1/4-5/2+4

     =  -1/2-3/4-5/2+4

      =[-1/2-5/2]-3/4+4

  =-6/2-3/4+4

   =-3-3/4+4

=[-3+4]-3/4

1-3/4

LCM=4

(1×4)-(3×1)/4

4-3/4

=1/4
