Question

Find the remainder of the polynomial x3+ 3x2+ 3x+1divided by x + 1​

Answer 1

Answer:

The remainder will be 0

Step-by-step explanation:

x+1=0

∴ x= -1

By substituting x in the equation:

p(x) = x³ + 3x² + 3x +1

p( -1)= -1³ + 3( -1)² + 3(-1) +1

     = -1 + 3 -3 +1

     = 0

∴ The remainder will be 0

Hope this helps you

Answer 2

Answer:

this will be done using the remainder theorem

Step-by-step explanation:

g(x)= x-1

g(x)= x-1 =0

= 1

f(x)= x3+3x2+3x+1

= (1)3 +3(1)2 +3*1 +1

= 1 +3*1 +3 + 1

=1+3+3+1

= 8
