@vagrant hill hi

vagrant hill
#

yo

#

Rishi!!!, my fave

cerulean dirge
#

do u need help with em all?

vagrant hill
#

i just need help with how todo it

#

ik i can use quadratic formula, but i dont think thats what it wants

cerulean dirge
#

so factoring

vagrant hill
#

probs since we learn quadratic formula2 excersices later

#

how do we factorise is it the sum and product method

cerulean dirge
#

yeah its that

#

move everything to one side of the equation so the right side is =0

#

then use the sum and product method

#

which is where u find two numbers that multiply to a*c and add to b, and then split ur x term into the two numbers and then group factor

vagrant hill
#

wait what

#

a*c?

#

i thought its multiply to =c and sum b

cerulean dirge
#

no its a*c

#

it didnt matter that much before tho cuz a=1 for most of ur previous problems

vagrant hill
#

ohh so when its one we use sum of abnd product of c?

cerulean dirge
#

i mean its still product of a*c

#

but when a=1, a*c=1*c=c

vagrant hill
#

yeah makes sense

#

can u show me how to do a

cerulean dirge
#

what are two numbers that multiplies to 9*4 and add to -12

#

since a=9, b=-12, c=4

vagrant hill
#

this is kinda hard since i actually dont know my times table

cerulean dirge
#

😭

#

i mean just run through the factor pairs of 36 (9*4)

#

(1,36), (2,18), (3,12), (4,9), (6,6)

#

and the obviously these pairs except both numbers are negative

#

then pick the correct pair

vagrant hill
#

ok

vagrant hill
#

so does itbecome 36x+12x=0

#

none sum to 12

#

@cerulean dirge

#

help bro idk

cerulean dirge
#

How did u split -12x into 36x and 12x?

vagrant hill
#

idk i just wrote stuff

cerulean dirge
#

U have to take the negative versions of all of these to get the full list

#

Like (-1,-36) for ex

#

So what pair of these would add to -12 and multiply to 36

vagrant hill
#

9 and 4

#

wait no

#

6 and 6

cerulean dirge
#

Ye

#

Well -6 and -6

#

Close enough

vagrant hill
#

ok then where do i sub em in

vagrant hill
#

bro idk man ive been tryin

#

this is my latest one 12(-6)+36(-6)=-288

vagrant hill
#
