Question

find the remainderx3+3x2+3x+1is divided by(v)5+2x

Answer 1

Step-by-step explanation:

To find the reminders we can use trial and error method or division method

here i am going to do in trial and error method.

first we should find the value of x.

5+2x=0

2x=-5

x=-5/2

so we should replace x as -5/2 in equation we can get,

-5/2^3 + 3(-5/2)^2+3(-5/2)+1

= -125/8+25/4-15/4+1

now we should find the lcm

lcm will be 8

-125/8 + 50/8 - 30/8 + 8/8

now we should simplify

-155/8 + 58/8

-97/8

the answer is -97/8
