Question

Factorise the following polynomial: 1 + 8x^3

Answer 1

Answer:

Step-by-step explanation:

1+8x^3         can be written as

1^3+2x^3                  using the identity a^3+b^3=(a+b)(a^2-ab+b^2)

where,a=1

           b=2x

so by equating we get

(1+2x)(1-2x+4x^2)=1+8x^3

so hence we factorized  1 + 8x^3

and found that the factors of it are

(1+2x) and(1-2x+4x^2)
