a. 
b. x = ∛-1 and -3
<h3>How to expand the expression</h3>
a. Given
(x² + 2)²
First, we open up the bracket

Multiply through

Collect like terms

b. Let's factorize

Find the factors of 3 that are products of 4, they are 3 and 1
Use it to replace 4x as 3x and x

Let's make the expression two

Find the common factor

So,
and 
and x = -3
Thus, x = ∛-1 and -3
