Question

Two algebra questions on conic sections?

Answer 1

Identify the conic. Write the equation.
x^2+3y^2+4x-3=8

I already know this one is an ellipse I just don't understand how to re-write the equation.

Answer 2

Okay the second question is basically the same thing with the equation
x^2-2y^2-4x-8y-26=0 and I know its a hyperbola.

Answer 3

What form u need to put these conic equations in? does the Q specify?

For the second eqn, u can look at the alternatie forms at wolfram here

https://www.wolframalpha.com/input/?i=x%5E2-2y%5E2-4x-8y-26%3D0

Answer 4

Just standard, I started to figure it out but i'm just confused.

Answer 5

u can express conic eqns in a number of forms n hence the alternate forms as shown on wolfram. did u check out the ones for ur second prob?

Answer 6

for the ellipse it's
(x-h)^2/a^2 + (y-k)^2/b^2

Answer 7

Oh okay u can enter the eqn from 1st prob in Wolfram n it will give u the values for h, k, a and b there :)

Answer 8

Okay(:

Answer 9

let me know if u run into any trouble :)

Answer 10

Where does it tell me what h,k a and b are???

Answer 11

foci n major n minor axis

Answer 12

Ohh okay, thank you tons(:

Answer 13

welcome u help urself 4 the most part :)
