Question

The polynomial x3+8 is equal to

Answer 1

The polynomial x3+8 is equal to (x+2)(x2-2x+4)

Answer 2

Polynomial (x + 2) (x² − 2x + 4 ).

Explanation:

Given : x³+ 2³.

To find : Solve .

Solution : We have given that x³+ 2³.

By the cubic formula : a³ + b³ = (a + b) (a² − ab + b² ).

Then

x³+ 2³ = (x + 2) (x² − 2x + 2² ).

x³+ 2³ = (x + 2) (x² − 2x + 4 ).

Therefore, Polynomial (x + 2) (x² − 2x + 4 ).
