Question

Find remainder when x^2+3x^2+3x+1
is divided by 5+2x​

Answer 1

Answer:

x^2+3x^2+3x+1 is divided by 5 + 2x

First we need to make 5+2x as a perfect value to find the remainder of the equation

So,5+2x=0

2x=-5

x=-5/2.

We got x value now substitute the value in x place of equation

x^2+3x^2+3x+1

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

{(25/4)+(75/4)}+{(-15/2)+1}

(100/4)+(-13/2)

25-13/2

50-13/2

37/2

So, it is not a perfect remainder

But overall,you get 37/2 is the remainder
