solve 6x-24x=126

OpenStudy (anonymous):

i got to \[\frac{ 24\pm \sqrt{-2448} }{ 12 }\]

OpenStudy (anonymous):

is this a quadratic equation?

OpenStudy (anonymous):

its written the same as the other one

OpenStudy (anonymous):

it doesnt say

OpenStudy (anonymous):

6x-24x=126

OpenStudy (anonymous):

there is no square

OpenStudy (anonymous):

how do i solve then?

OpenStudy (anonymous):

the answers are like the other one too

OpenStudy (anonymous):

just checking, you wrote the equation correctly? 6x-24x=126

OpenStudy (anonymous):

oooo no i did not the 6x is 6x^2

OpenStudy (anonymous):

other then that yes

OpenStudy (anonymous):

this changes alot

OpenStudy (anonymous):

6x^2-24x=126

OpenStudy (anonymous):

now you can solve with the quadratic formula

OpenStudy (anonymous):

i tried that but -2448 doesnt square and thats what i got for inside the √

OpenStudy (anonymous):

hmm

OpenStudy (anonymous):

i got it i had signs messed up

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

remember, 6x^2 + (-24x) + (-126)

OpenStudy (anonymous):

= 0

OpenStudy (anonymous):

i'll have to leave after this one, if you have any questions, now's the time to ask them

OpenStudy (anonymous):

i posted another one but i dont have any other questions for this one

OpenStudy (anonymous):

the other one is exactly the same, just different numbers

OpenStudy (anonymous):

i'm stuck on the √ again
