Answer:

Step-by-step explanation:
For example, we'll use this quadratic equation.

To understand how to plug it into the formula we need to know what each term represents.

So the equation above would be put into the formula like this.

Then we would solve

Now, the equation will branch off into one that solves when addition and one when subtraction.

So x={-3, -2} (-3 and -2)

Answer with explanation:
If Submarine position is 600 feet below sea level, it can be represented in terms of integers as = - 600
Now , it descends 218 feet ,from where it is presently Located.
Descend in terms of integers can be represented as = - 218 feet
Submarine New position or Elevation = - 600 feet + (-218 feet)
= -818 feet
Option A : -818 feet
