Answer 1

Answer:

p(x)=x⁴-2x³+3x²-ax+b

x=1 ;x= -1

p(1)=1⁴-2(1)³+3(1)²-a(1)+b

  5  =1-2+3-a+b

   5 =2-a+b

  a-b=-3---------- 1

p(-1)=(-1)⁴-2(-1)³+3(-1)²-a(-1)+b

   19 =1+2+3+a+b

   a+b=13----------2

from 1 and 2

a-b=-3

a+b=13

2a=10

a=5

a-b=-3

5-b=-3

b=8

p(x)=x⁴-2x³+3x²-5x+8

x-2=0

x=2

p(2)=2⁴-2(2)³+3(2)²-5(2)+8

     =16-16+12-10+8

    =20-10=10

remainder=10
