OpenStudy (anonymous):

u should complete the square

OpenStudy (anonymous):

divide coefficient of x by 2

OpenStudy (anonymous):

then u get first number in brackets

OpenStudy (anonymous):

okay so I complete the square but the rest I dont kow how to do.

OpenStudy (anonymous):

i gave u the first hint

OpenStudy (anonymous):

then square that number u get 49... -49+42=-7 so u get 7 the second missing number

OpenStudy (anonymous):

this is what I got completing the square

OpenStudy (anonymous):

this is right :)

OpenStudy (anonymous):

Good

OpenStudy (anonymous):

Okay, so now what. How do I get the form?

OpenStudy (anonymous):

The form is 7 in missing blanks

OpenStudy (anonymous):

both of them are 7?

OpenStudy (anonymous):

yup

OpenStudy (anonymous):

and the one with + or -?

OpenStudy (anonymous):

that was the answer for x

OpenStudy (anonymous):

as a result of squaring u get + _

OpenStudy (anonymous):

oh okay so x=7 so how do I find the form?

OpenStudy (anonymous):

nop. x was what you wrote -7+ - sqrt7

OpenStudy (anonymous):

okay I don't know what your saying. where do I put the 7?

OpenStudy (anonymous):

in both missing squares

OpenStudy (anonymous):

u choose the first with + form

OpenStudy (anonymous):

okay but the one with the + or the -, i cannot put the answer in both it has to be one of the other

OpenStudy (anonymous):

+form

OpenStudy (anonymous):

okay so +

OpenStudy (anonymous):

aha

OpenStudy (anonymous):

is it good ?

OpenStudy (anonymous):

like this?

OpenStudy (anonymous):

@mlearning24

OpenStudy (anonymous):

yup true

OpenStudy (anonymous):

okay so what about x= ?

OpenStudy (anonymous):

-7+-sqrt7

OpenStudy (anonymous):

It has to be in decimal form

OpenStudy (anonymous):

so calculate it on

OpenStudy (anonymous):

both - and +

OpenStudy (anonymous):

use calculator for: -7+sqrt7

OpenStudy (anonymous):

use calculator for -7-sqrt7

OpenStudy (anonymous):

what do I calculate? and shouldnt it be radical 7?

OpenStudy (anonymous):

separate answers with commas

OpenStudy (anonymous):

round nearest hundredth

OpenStudy (anonymous):

so -4.35 and -9.65?

OpenStudy (anonymous):

perfect

OpenStudy (anonymous):

I guess am done :)

OpenStudy (anonymous):

I have another same kind of problem

OpenStudy (anonymous):

ops. do it and I check if it is right :)

OpenStudy (anonymous):

u can open a new quest

OpenStudy (anonymous):

I'm just really having trouble on how I get the form. That's the only thing I'm not understanding
