Question

anonymous · Answer

Part 1. 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

Use a constant in place of each variable a, b, c, and d. You can use positive and negative constants in your equation. 

Part 2. Show your work in solving the equation. Include the work to check your solution and show that your solution is extraneous. 

Part 3. Explain why the first equation has an extraneous solution and the second does not.

Is the "b" under the radical?

$a\sqrt{x+b} + c = 0$

Solving without regard to anything.

$a\sqrt{x+b} = -c$ <== Here's an opportunity.  What if x + b < 0?!

$\sqrt{x+b} = -c/a$ <== Here's an opportunity.  What if c/a < 0?!

$x+b = -c^{2}/a^{2}$

$x = - b - c^{2}/a^{2}$

Play around with:

1) $x+b\ge 0\;vs\;x+b<0$
2) $a\cdot c \ge 0\;vs\;a\cdot c < 0$

what do you mean

anonymous · Answer

yes it is over the b

I mean all that is written above.  This is an EXPLORATION problem.  There is not a BEST answer.  You must EXPLORE it.  I gave you two things to explore.  Read it carefully and have fun!

Thanks @tkhunny :)

anonymous · Answer

which has an extraneous solution and which doesn't?

wtf?

anonymous · Answer

lol lmao

anonymous · Answer

Alright, I got this. I just used u-substitution to find the initial state of a qubit before it is observed in a plus/minus basis then used Grover's Algorithm to search through a lattice of N-index. After that, you should end up with a 100000000 variable partial diffy-q.

And that my friends, explains women.

anonymous · Answer

that makes perfect sense!

anonymous · Answer

I know :D Now I know how to take out Kim Kardashian!

anonymous · Answer

lol perfect equation! gotta see if my math teacher can solve it, probably not he cant get women lol

anonymous · Answer

That's perfect for him, I used it on my mom last night.

anonymous · Answer

lol which way did you solve it behind or in front? Did you feel the transvaginal mesh?

anonymous · Answer

gonna close the question bye :)

anonymous · Answer

I actually solved it from the side.  Side is the best.
