Question

solve the following:-

Find the remainder x^2 + 3x^2 +3x+1 is divied by x + 1
​

Answer 1

Answer:

2.

Step-by-step explanation:

$x^{2}$+$3$$x^{2}$+$3$$x$+$1$ ÷ $x$$+$$1$

x+1 can also be written as x+1=0

Or x=(-1)

By substitution method after substituting the value of x in the equation we get.

= $(-1)^{2}$ + 3 $(-1)^{2}$ + 3×(-1) +1

as we know, square of a negative value is a positive value.

= 1+3-3+1

= 2.
