Plz Answer this question

Answer 1

The answer is
`4a(16a^2+27b^2)-3b(9b^2+48b)`

Explanation:

step one:

let us re-write the expression in mathematical terms for clarity

we have the expression stated below

`64a^3-27b^3-144b^2+108ab^2`

step two:

We are going to collect like terms before factorization we have

`64a^3+108ab^2-27b^3-144b^2`

We can now factorize the expression we have

`4a(16a^2+27b^2)-3b(9b^2+48b)`
