Question

How do you convert y-5=-2(x+1)^2 to standard and intercept modes?

Answer 1

Well, add 5 and that's usually Vertex Form.
Then, multiply out and simplify the right side for Standard Form.

Answer 2

Yeah, but the factoring is what is so tricky

Answer 3

Factoring? There is no need to factor. It is already in a factored form.

Do you need to find zeros?

Answer 4

yes, the form it currently holds is vertex. To get to intercept form, You must factor from standard

Answer 5

Factor or solve. Put it in Standard Form and see how easy it is.

Answer 6

I did put it into standard form, and I got y= -2x^2-4x+3
remember the y-5 on the other side

Answer 7

y-5=-2(x+1)^2
y-5 = -2(x^2 + 2x + 1)
y-5 = -2x^2 - 4x - 2
y = -2x^2 - 4x +3

Do you know the Discriminant? It will tell you that this cannot be factored. Just use the Quadratic Formula.

Answer 8

So how am I supposed to answer the question for putting it in standard form?
Also, I need to graph it and I'm just getting confused with what they expect here

Answer 9

My own idiocy surprises me sometimes, it is able to be graphed.

Answer 10

Thanks so much
