Quincy uses the quadratic formula to solve for the values of x in a quadratic equation. He finds the solution, in simplest radic
al form, to be x = 
.
Which best describes how many real number solutions the equation has?
A. Zero, because the discriminant is negative.
B. Zero, because the discriminant is not a perfect square.
C. One, because the negative and the minus cancel each other out.
D. Two, because of the ± symbol.

Answer:
Step-by-step explanation:
For this case we have the following value:
We can convert this first to like this:
Now we use the fact the the pressure is defined as , whre P is the pressure, F the force and A the area, so then
and then we can replace this:
Now from definition of work we know that where W is the work, F the force and d the distance, so then is equivalent
And if we replace this into the equation we got:
The reciprocal of a fraction 
is the same fraction "upside down" 
.
The reciprocal of a whole number
is "1 over" that number 
.
