Question

Please help factoring!
x^2+8x+4y+8=0

Answer 1

x^2+8x__= 4y+8

Answer 2

@Hero

Answer 3

Its a parabola that I need to write in standard form, find vertex, focus,directrix, and axis of symmetry

Answer 4

(x-h)^2=4p(y-k)

Answer 5

x^2+8x__= 4y+8
Add 16 both side and complete the square on the left hand

Answer 6

so vertex is (4,-6)

Answer 7

(that should be a 4(y+6)

Answer 8

Your equation is x^2+8x+4y+8=0. right ?

Answer 9

yep

Answer 10

Then you should have x^2 + 8x = -4y - 8

Answer 11

really? ok then vertex is (4,-2)

Answer 12

and p=-1

Answer 13

how do i find the focus,symmetry, and directrix?

Answer 14

Vertex should be 4,2

Answer 15

oh thats right, theres a -4...

Answer 16

can you qualitatively draw this parabola ?

Answer 17

ummm im not sure...

Answer 18

i can plot the vertex but i dont know any points on the parabola curve
