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

Option C) Smith have to pay $180 at the time of purchase.
<u>Step-by-step explanation:</u>
Mrs. Smith wants to use an installment plan to buy a washing machine and dryer set priced at $1,500.
- Therefore, the total cost = $1500
- The down payment for the installment plan is 12%.
We need to find the payment amount at the time of purchase.
This can be calculated by finding the 12% of the total price $1500.
Smith have to pay at the time of purchase = 12% of 1500
⇒ (12/100) × 1500
⇒ 12 × 15
⇒ 180
Hence, option C) $180 is the amount need to be paid by the Smith at the time of purchase.
2x = 2 * 3 = 6
6^2 = 6*6 = 36
36 + 3 = 39
