substituting -1/3 by x

we get

(-1/3)³+3×(-1/3)²+3×-1/3+1

-1/27+1/3-1+1

=-1/27+1/3

=8/27

The Brainliest Answer!

1. first equate the divisor( or 3x+1) to 0 and find the value of x.

so 3x + 1 = 0

⇒ 3x = -1

⇒ x = -1/3

2. Now find the value of the dividend( or x³ + 3x² +3x +1) at that value of x.

putting x = -1/3

x³ + 3x² +3x +1

= (-1/3)³ + 3×(-1/3)² + 3×(-1/3) + 1

= -1/27 + 3×(1/9) + 3×(-1/3) + 1

= -1/27 + 1/3 - 1 + 1

= 1/3 - 1/27

= (9-1) / 27

= 8/27
