#

just dont get the -4ac

#

everytime i try it i get it wrong

#

and i pretty sure i do the calculations right

#

maybe just takin the wrong steps

pearl chasm Oct 9, 2023, 8:48 PM

#

show steps?

#

also you can factor this one

errant pivot Oct 9, 2023, 8:49 PM

#

you put into the equation..

pearl chasm Oct 9, 2023, 8:49 PM

#

could you take a scrn of your work so far

#

or picture

errant pivot Oct 9, 2023, 8:49 PM

#

its quesiton by question#

#

so you cant really go back

#

x=-(-5) square root -5^2-4 (1)(6)

#

is that correct

pearl chasm Oct 9, 2023, 8:52 PM

#

yea

errant pivot Oct 9, 2023, 8:53 PM

#

so it become 5 +/- root -5 -12

#

????

pearl chasm Oct 9, 2023, 8:53 PM

#

what

#

how did you simplfy the root part

#

$\sqrt{(-5)^{2}-4(1)(6)}$

!𒐪 ɹɐupoɯ⇂ㄥ8𝟝 𒐪!

errant pivot Oct 9, 2023, 8:55 PM

#

pearl chasm how did you simplfy the root part

dont u just root -4 and -5

pearl chasm Oct 9, 2023, 8:55 PM

#

you cant just split the root up

errant pivot Oct 9, 2023, 8:55 PM

#

oh

#

now im confused

#

what do i do with it then

pearl chasm Oct 9, 2023, 8:57 PM

#

simplify whats in the root

errant pivot Oct 9, 2023, 8:58 PM

#

so i get rid of the square?

#

Hold on

#

I think i got it

#

Would it be 5-24

#

So -19

pearl chasm Oct 9, 2023, 9:04 PM

#

whats (-5)^2

errant pivot Oct 9, 2023, 9:04 PM

#

25

pearl chasm Oct 9, 2023, 9:07 PM

#

errant pivot Would it be 5-24

so what should this be

errant pivot Oct 9, 2023, 9:08 PM

#

-19

#

omg ur right

#

#

its not -19

#

its 1

#

thanksss

#

i get it now

pearl chasm Oct 9, 2023, 9:08 PM

#

yay!

errant pivot Oct 9, 2023, 9:08 PM

#

ive tried the assignment 3 times

#

i finally got it

#

@pearl chasm sorry about this

#

#

but i did the same working and got it wrong

pearl chasm Oct 9, 2023, 9:13 PM

#

can you show me your work for the square root again please

errant pivot Oct 9, 2023, 9:14 PM

#

root -3^2 -4(2)(-5)

pearl chasm Oct 9, 2023, 9:14 PM

#

keep going

errant pivot Oct 9, 2023, 9:14 PM

#

-3^2=9

#

4* 2 *-5=-40

#

9-40=-31

pearl chasm Oct 9, 2023, 9:15 PM

#

you can do this btw

pearl chasm Oct 9, 2023, 9:15 PM

#

errant pivot 9-40=-31

9-(-40)

errant pivot Oct 9, 2023, 9:15 PM

#

ohhh

#

so that =49

#

root 49 is 7

pearl chasm Oct 9, 2023, 9:16 PM

#

yes

errant pivot Oct 9, 2023, 9:16 PM

#

so sorry btw

#

its just abit confusin

pearl chasm Oct 9, 2023, 9:16 PM

#

nah its fine
