Question

Show your work in solving the equation. Include the work to check your solution and show that your solution is extraneous

Answer 1

I need help on how to do an extraneous equation on radicals

Answer 2

what is the question you need help on\

Answer 3

I need help on this one I already got my numbers

. Create two radical equations: one that has an extraneous solution, and one that does not have an extraneous solution. Use the equation below as a model.
a√x+b+c=d

Answer 4

I do not know how to make an extraneous problem

Answer 5

An extraneous solution is a root of a transformed equation that is not a root of the original equation because it was excluded from the domain of the original equation.

Example 1:

Solve for xx , 1x − 2+1x + 2=4(x − 2)(x + 2)1x − 2+1x + 2=4(x − 2)(x + 2) .

1x − 2+1x + 2=4(x − 2)(x + 2)1x − 2+1x + 2=4(x − 2)(x + 2)

(x − 2)(x + 2)(x − 2)+(x − 2)(x + 2)(x + 2)=4(x − 2)(x + 2)(x − 2)(x + 2)(x − 2)(x + 2)(x − 2)+(x − 2)(x + 2)(x + 2)=4(x − 2)(x + 2)(x − 2)(x + 2)

(x−2)+(x+2)=4(x−2)+(x+2)=4

2x=42x=4

x=2x=2

But 22 is excluded from the domain of the original equation because it would make the denominator of one of the fractions zero--and division by zero is not allowed! . Therefore, it cannot be a root of the original equation. So, 22 is an extraneous solution. So, the equation has no solutions.

Answer 6

Ok but how would I do it with these numbers I do not want you to tell me just guide me


they are -
2
6
4
8
What order should I put them in I already tried this once and got this part wrong.

Answer 7

It is in task 2

Answer 8

Step 1 :

Pulling out like terms :

1.1 Pull out like factors :

2x + 2 = 2 • (x + 1)

Equation at the end of step 1 :

Step 2 :

Equations which are never true :

2.1 Solve : 2 = 0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2 Solve : x+1 = 0

Subtract 1 from both sides of the equation :
x = -1



x = -1

Answer 9

kind of like this?

Answer 10

My teacher wants with radicals and I am not good with radicals

@3mar

Answer 13

Well, I am here.
I was praying!

Answer 14

ok cool

could you help me on task 2 on the extraneous problem

Answer 15

Ok.
But if you are not in hurry, it would take some time!

Answer 16

im not

Answer 17

That is good!

Answer 18

doyou know my numbers?

Answer 19

" my numbers?"???

Answer 20

Ok.

What you got for part 1?

Answer 21

That part was just to show the numbers I picked

Answer 22

they are 2, 4, 6, 8 how do I make an extraneous problem out of those numbers?

Answer 23

@3mar

Answer 24

Time for pray - 15 min
I will be back In Sha' Allah after 12-20 min

Answer 25

are you there?

Answer 26

I am here now

Answer 27

Ok could you help me?

Answer 28

After you did
what is the question?
