Question

3.Substitute your birthday into the equation Square root of the quantity x minus y + m = d, where y is the last two digits of your birth year, m is the month, and d is the day. If you were born on 7/10/1856 like Nikola Tesla, your equation would be Square root of the quantity x minus 56 + 7 = 10. Solve for x and identify if it is an extraneous solution. My birthday is 06/06/1998
who ever answers this I will give a medal to.

Answer 1

Dang my birthday is May 9th 1997! This seems a little tricky

Answer 2

I know I tried asking my teacher but he wouldn't help me .-.

Answer 3

What's stopping you from doing what the example showed you?

Answer 4

So I got \[\sqrt{x-98} +6=6\]

Answer 5

But I don't know if the question is asking for this: \[\sqrt{x-98} +6=6\] or this: \[\sqrt{x-98+6}=6\]

Answer 6

I got sqrt x-98 +6=6 I just don't understand how to solve the equation

Answer 7

Ok, but answer what chris has asked you, please specify your equation.

Answer 8

Is it \[\sqrt{x-98}+6=6 ~~~~ \text{or}~~~\sqrt{x-98+6}=6\]...

Answer 9

\[\sqrt{x-98} +6=6\] is what I got

Answer 10

Ok good, so now you want to look for the extraneous solution

Answer 11

So we want to solve for x right?

Answer 12

Yes wouldn't we square the x-98 to get rid of the square root?

Answer 13

Right! See you know this stuff :)

Answer 14

And what's next?

Answer 15

First lets simplify it a bit, move the 6 on the right

Answer 16

Then we'll take the square root

Answer 17

So we take the square root of the 6 right?

Answer 18

Yes, so your left with x-98 + 6 = 6

Answer 19

Well I meant, lets make it easier on ourselves by doing this \[\sqrt{x-98}-6=6 \implies \sqrt{x-98} = 12\]

Answer 20

You know what to do from here?

Answer 21

Yes thank you guys so much for the help!

Answer 22

Np, everything make sense now?
