Answer:
Here, 
, hence the quadratic equation has two distinct real roots.
Step-by-step explanation:
Given quadratic equation is 
.
Let, the quadratic equation is 
[where, 
are the constants]
The Discriminant 
Case 
: 
, if the discriminant is greater than 
, it means the quadratic equation has two real distinct roots.
Case 
: 
, if the discriminant is less than , it means the quadratic equation has no real roots.
Case 
: 
, if the discriminants is equal to , it means the quadratic equation has two real identical roots.
Now,
we have , where 
∴
Here, , hence the quadratic equation has two distinct real roots.
Assuming this is a rectangular prism, here are the formulas for the volume and surface area.
V=l×w×h
SA=lw+lw+lh+lh+wh+wh
