Question
Solve the radical equation 
Check for extraneous solutions
Hint:
Rearrange the equation and then solve for x.
The correct answer is: Hence no extraneous solution
Complete step by step solution:
Here we have the equation
On squaring both the sides, we have 
On rearranging, we have 
Now, this is a quadratic equation with a = 4, b =-17, c = 15
Roots can be found with, 
On solving, we get 
Here, on substituting 
in given equation we get
Hence x = 3 works.
Now 
Hence 
works.

The rate at which an object move is refers as its speed. If an object has traveled far away from the initial place and how much time it takes? To be calculated using the average speed traveled by an object. The speed formula is speed = distance/time. To determine the units for speed, we must consider the units for distance and time.
There are three different ways to write the formula. They are:
• speed = distance ÷ time
• distance = speed × time
• time = distance ÷ speed
Here speed, distance, and time are internally linked. So, to calculate the value of among one, we require another unit.
For example, to determine the time required to complete a journey, we must know the distance and speed first.

The quantity of goods in general that will be exchanged for one unit of money is then the value of money. Money's value is defined as its purchasing power, or the amount of goods and services it can buy.
The time value of money (TVM) is the idea that a sum of money is worth more now than it will be at a later date because of the potential earnings in the interim. A sum of money in hand is more valuable than the same sum to be paid later. The time value of money is another name for the present discounted value.
