Find the roots

glad tinsel
#

how

#

wai

#

t

#

-7

#

-2

hollow rose
#

Yes

honest edge
#

</ 0 means you want the range under the graph

hollow rose
#

Curve crosses -7 and -2 when y = 0

glad tinsel
#

yes

#

right

#

but

#

how do i get the inequality

#

solved

honest edge
#

sketch it

hollow rose
glad tinsel
#

i did

honest edge
#

now consider the values under the graph

#

and write it as an inequality

glad tinsel
#

i dont get that part

#

like i

#

k

hollow rose
glad tinsel
#

yes

#

so -2 si more than x?

#

ikd

honest edge
#

you want the values in between that -7 and -2

glad tinsel
#

yj

#

yh

honest edge
#

which since its <

hollow rose
#

Don’t forget the equal to sign

honest edge
#

Will be anything greater than or equal to -7

glad tinsel
#

oh i forgot abotu that

honest edge
#

and less than or equal to -2

glad tinsel
#

ohhh

#

one sec

#

huh

#

wait nvm

#

is it the 5th

honest edge
#

just has gave some options

honest edge
glad tinsel
#

thx

honest edge
#

oh wait

glad tinsel
#

wait

#

so how do the first opetions

#

have 2 seperate

honest edge
#

you can't write two separate inequality signs as 1 combined inequality

glad tinsel
#

why not

honest edge
#

bc you wouldn't get the correct inequality region

glad tinsel
#

is it still the 5th one

honest edge
#

yeah

glad tinsel
#

so when woudl it be the first 2

honest edge
#

it's a bit finicky what you have to consider

honest edge
glad tinsel
#

so i js have to rememr the signm

honest edge
#

which would be everything above the x axis

#

and so it just continues onto infinity

glad tinsel
#

oh yeah

#

cause its not joined

#

so u cant

#

thingy

#

yes

honest edge
#

yeah

glad tinsel
#

that makes sens

#

thx

honest edge
#

np

glad tinsel
#

?

honest edge
#

sketch it

#

and have a look

glad tinsel
#

i did

#

but is it right

honest edge
#

,w sketch x²-9x+18>0

plush spireBOT
honest edge
#

yes

#

Nice one

hollow rose
#

Wait until you get onto modulus functions 😭

#

I get stuck finding the inequalities

glad tinsel
honest edge
#

,w sketch |x-1|>3

plush spireBOT
glad tinsel
#

whys it truangula

honest edge
#

yeah I don't know how modulus works graphically, only algebraically

hollow rose
#

Because it cannot go negative

glad tinsel
#

weird

honest edge
hollow rose
honest edge
#

|-3|=3

glad tinsel
#

its fine il worry about it when i need to

honest edge
#

always

glad tinsel
#

casue factorised its x(x-7)

honest edge
glad tinsel
#

idk

#

0

honest edge
#

think about it like two separate brackets

#

yeah 0

#

andddd

glad tinsel
#

oh

#

7

honest edge
#

boom

hollow rose
#

🥳

hollow rose
#

Recognise the font

glad tinsel
#

yeah

#

dparx

#

sparx

honest edge
#

sparx 🤢

hollow rose
#

Ew

#

I had mymaths and hegarty

honest edge
#

I had mathswatch and have now drfrostmaths and the textbook

hollow rose
#

Wish I got textbook for hw

#

Teachers make their own questions and they make so many errors mgod

glad tinsel
#

finally done

#

😍

honest edge
#

Well done

#

I have yet to do daily maths and physics

glad tinsel
#

i only have 9hrs of hw left

hollow rose
#

Dw maths mentors will help

#

(They all automatically fall asleep after midnight)
