A= B x h
Where b is the base and h is the height
What? You bought a call with options, and 50 lightning??
Hi :)
I'd start by adding 5 to both sides of the equation. That would make the equation easier.


The next step is to get rid of the radical sign.
Which operation will undo the square root? Squaring.
So that's why we square both sides:

And Now we just divide both sides by 2

The value of x is -15.
Work:
x + 9 = -6
Move the 9 by subtracting from both sides.
x + 9 - 9 = -6 - 9
x = -15
Therefore x is -15.
The remainder theorem tells you that when you do synthetic division with the 6, the remainder will be the same value as when you evaluate the function with the value of 6.
The answer is 15
