Step-by-step explanation:
It's basic math.
<span>An extraneous solution is a solution, such as that to an equation, that emerges from the process of solving the problem but is not a valid solution to the original problem.
Given the equation:

From the equation, it is obtained that x = 1 and x = -4 are the solutions of the equation.
Now, we substitute x = 1 into the equation as follows:
</span><span>

As can be see, for x = 1, the equation is undefined.
Now, we substitute x = -4 into the equation as follows:

It can be seen that x = -4 is a valid solution of the orignal equation.
Therefore, x = 1 is an extraneous solution to the equation

Step-by-step explanation:
Use inverse operations to work the problem backwards.
Ball final speed = 209 km/hr = 58.12 m/s
Racket displacement = 0.1 meters
Using the equation of motion:
2as = v² - u²
Where the initial velocity u is 0
a = (58.12)²/2 * 0.1
a = 16,889.7 m/s²
