120 + 30 = 150
66/11 = 6
26-3x8 = 184
17-4x4 = 52
150/6 = 25
184 + 52 = 236

Answer:
x=-6 is an extraneous solution
Step-by-step explanation:
we have

squared both sides



solve the quadratic equation by graphing
The solution is x=-6 and x=-1
see the attached figure
<u><em>Verify each solution</em></u>
substitute the value of x in the original expression
For x=-6


----> is not true
so
Is an extraneous solution
For x=-1


----> is true
so
Is the solution
