plugin the numbers into the given equation ?

\(\large \sqrt{x-y} + m = d\)

y is last two digits of ur birth year (u may fake if u want ;) )
m is month
d is day

Okay

wat do u get for the equation ?

Let me work it out

okie

I can't get the answer .. I don't know how to work this out ! :(

if u can show me wat do u have... maybe i can help :)

did u plugin the values in equation ?

\(\large \sqrt{x-y} + m = d\)
^

Okay

put the year u born in that place

which year ?

Don't I use the values given in the question ?

Ohhh nevermind , I just read the question wrong . My bad

No, those values are for ur great great grandpa Nikola Tesla....
they're not urs lol

cool :)

Okay so I was born in 96

\(\large \sqrt{x-96} + m = d\)
^

there it goes !
wat about month and date

i feel like im interviewing u lol

Haha month is 4 and day is 22

thanks for giving it one shot :)

\(\large \sqrt{x-96} + 4 = 22\)

Alright so now what to do :o

solve for x

start by subtracting 4 both sides

Okay

\(\large \sqrt{x-96} + 4 = 22\)
subtract 4 both sides
\(\large \sqrt{x-96} = 18\)

18

Yes ! next, square both sides

You mean square 96 and 18 ?? :o

like this..

since u r not happy wid radical, we're killing it by squaring both sides !

Oh okay !

wats our next step ?

Add 96 to both sides ?

thats it !

Okay so that would be 420 ? (;

Yes ! good job !!

oh, it asks to check if the solution is extraneous or now.

*not

Yeah , I don't know what that means .

its very easy to check,
simply put the solution u got for x in the original (ur bday ) equaiton

Alright

I worked it out and I got 420=324 :o

careful, check again

But that's not true , so does that mean the solution IS extraneous ?

Oh okay ..

i want u check again,

Right

Ohhhh okay ! That makes more sense !

THANK YOU

np :) yw !
