Step-by-step explanation:
Open the brackets
-x is the same as -1x
(2
x -
)(3
)
- The bases will be multiplied while the powers will be multipled
-2
x 3
- In the law of indices(multiplication), provided the bases are equal,they are to be added.
-6 
= -6
Since the discriminant is positive, this means we have two distinct real solutions.
If a, b, and c are rational numbers, then a discriminant of D = 40 indicates the two solutions are not rational. We would need D to be a perfect square to get two rational solutions.
