Question

x^3+3x^2+3x+1÷x+1 what is the reminder? please explain its urgent..

Answer 1

Answer:

zero

Step-by-step explanation:

x³+3x²+3x+1  ÷  x+1   => remainder=?

==========

we can group the polynomial as:

• (x³+1)+(3x²+3x)
• = (x+1)(x²-x+1)+3(x+1)
• = (x+1)(x²-x+1+3)
• =(x+1)(x²-x+4)

as we see it has a factor of x+1 and as such it is fully divisible by x+1

so the remainder is zero
