Hello from MrBillDoesMath!
Answer: A, C, D
Discussion:
The solution of the quadratic equation ax^2 + bx + c = 0 is
x = ( -b +\- (b^2 - 4ac) ^ (1/2) ) /2a
The expression b^2 - 4ac is called the discriminant, occurs in the numerator of the solution, and also occurs inside a square root (called a radicand).
The question, while intelligible, should be stated more clearly.

Answer:
-6
-6i
6i
6
Step-by-step explanation:
1) √4 . √-3 . √-3
-6
2) √-4 . √-3 . √-3
.
Therefore, 
- 6i
3) √4 . √3 . √-3
6i
4) √4 . √3 . √3
Therefore, √4 . √3 . √3 = 2 . 3 = 6
30% of 42 is 12.6$.
42-12.6 = 29.4$ is the price of the pair with discount applied.
Tax 7%
29.4 * 7% = 2.06
29.4$ + 2.06$ = 31.46 $ final price with discount and tax applied.
