Factor using the identity: a3 + b3 = (a + b)(a2 – ab + b2) 8z3 + 27

vivado [14]

Answer: this is our required factor i.e.

$8z^3+27=(2z+3)(4z^2-6z+9)$

Explanation:

Since we have given that

$8z^3+27$

As we know the identity , which says that

$a^3+b^3=(a+b)(a^2-ab+b^2)$

So, we can use this here ,

$8z^3+27=(2z)^3+3^3\\\\=(2z+3)((2z)^2-2z\times 3+3^2)\\\\=(2z+3)(4z^2-6z+9)$

Hence this is our required factor i.e.

$8z^3+27=(2z+3)(4z^2-6z+9)$
