Question

Can somebody please help me

Answer 1

so we did rows 1 and 2 earlier, let me know if you still want to go over those

https://questioncove.com/study#/updates/5a29eec523435f49ceecec00

for row 3, start by expanding the intercept form using foil to get standard form

Answer 2

for the second row intercept form i did not get

Answer 3

iirc it wasn't factorable and we had to use software to get something :/

Answer 4

well for row 2
standard form y=-2x^2-4x+3
vertex form y-5=-2(x+1)^2

Answer 5

The intercept I did not get

Answer 6

I'll ask around and see what others have to say about it

Answer 7

Sounds good

Answer 8

well for row three in the meantime, the vertex form is this right?

Answer 9

yeah, that's it, since vertex form is already given

Answer 10

No i meant the third row where the intercept is given would this be the vertex form?

Answer 11

yeah, but since the question formats their vertex forms like y + k = (x-h)^2 I would just take that output and add (25/4) to both sides

Answer 12

so y+25=(x-1/2)^2-4

Answer 13

oh okay so that would be the vertex form for row three

Answer 14

yes

Answer 15

what about standard

Answer 16

just take the intercept form and expand it using foil

Answer 17

y=25+4x?

Answer 18

y = (x+2)(x-3) = ?

Answer 19

x^2+3x+2x+6

Answer 20

Answer 21

@563blackghost

Answer 22

make sure you are considering the negative sign in front of the 3

you can re-write the function as y = (x+2)(x + (-3) ) if that makes it easier

Answer 23

x^2-x-6?

Answer 24

Sorry I was afk

Answer 25

@Vocaloid

Answer 26

Yeah that's correct

Answer 27

so would that be the standard form for the third row?

Answer 28

Yes

Answer 29

okay and did you by chance get to figure out the intercept form for the second row

Answer 30

Not yet

Answer 31

You could tag sillybilly maybe
