Two possible solutions of √11-2x=√x^2+4x+4 are –7 and 1. which statement is true? a) only x = –7 is an extraneous solution.
b) only x = 1 is an extraneous solution.
c) both solutions are extraneous.
d)neither solution is extraneous.

Option D)Neither solution is extraneous.

Step-by-step explanation:

we have

we know that

two possible solutions are x=-7 and x=1

Verify each solution

Substitute each value of x in the expression above and interpret the results

1) For x=-7

----> is true

therefore

x=-7 is not a an extraneous solution

2) For x=1

----> is true

therefore

x=1 is not a an extraneous solution

therefore

Neither solution is extraneous

definitely a. the others have almost all data points on one side of the line.
