Answer 1

problem

Answer 2

One way to solve the problem is to plug in the values to see if they equal each other.

Answer 3

Add 5 to both sides and then square both sides

{sqrt(x+6)}^2= (x+6)^2

Answer 4

You can solve the equation and check the solutions in the original equation or you can test the given answers in the equation and see if they make the sentence true.

Answer 5

@Mertsj @cjr712 @KirbyLegs I keep going back to option C. but i dont know. really rusty on all these concepts, its been a year.

Answer 6

sqrt(x+6) = x + 6

when sqrt(A) = A, A is either 0 or 1.

Answer 7

@Mertsj ill just apply each given answer

Answer 8

That's the simplest thing to do in this situation.

Answer 9

when you square a square root, whatever is inside comes out, so you'll have x+6 on the left side and (x+6)^2 on the right side which when you foil out it comes out to x^2+12x+36

Answer 10

@cjr712 i am still stuck with C

Answer 11

That's because it says non extraneous solutions

Answer 12

one of the numbers in C does not work

Answer 13

@cjr712 what do you mean?

Answer 14

@cjr712 ahhhh hold on then. redo.

Answer 15

@cjr712 im not understanding. neither -2 or -6 work.

Answer 16

-6 works

Answer 17

sqrt of 0 is 0 -5 is -5 and -6+1 is -5 so -5=-5

Answer 18

be careful of the wording make sure you understand what they're asking so you can answer correctly

Answer 19

@cjr712 so then it is -2? since it is saying nonextraneous and 2 does not work

Answer 20

-2**

Answer 21

-2 is extraneous since it doesnt work. -6 is non extraneous. that is the meaning of it,

Answer 22

@cjr712 ohh, i reversed their meaning

Answer 23

:)

Answer 24

@cjr712 ty!!
