Answer:
Step-by-step explanation:
We are given with two equations
first equation is
second equation is
we find the result of subtracting two equation
subtract the second equation from the first, so
first equation - second equation, multiply second equation by -1 and then add it with first equation
Now add both equations, we get
Answer:
x=8 is a true solution of the radical equation
Step-by-step explanation:
we have
Solve for x
squared both sides
Convert to factored form
The solutions are x=2 and x=8
<u><em>Verify the solutions</em></u>
For x=2
Substitute in the original equation
----> is not true
therefore
x=2 is not a true solution of the radical equation
For x=8
Substitute in the original equation
----> is true
therefore
x=8 is a true solution of the radical equation
