A isn't included because it's not right.
DivineSolar (divinesolar):
With that there is no real solution.

So my answer would be B?
DivineSolar (divinesolar):
Most likely yes, Mind you I did solve this, not graph. So again I could be wrong.
OpenStudy (anonymous):
thank you

What about this, -4x^4 - 44x^2 + 3600 = 0

now what do I do?
DivineSolar (divinesolar):
Solve the last part an tell me what you get, you should have two of the x='s
OpenStudy (anonymous):
I have answer choices.
A. 5, -5, 6i, -6i
B. 5, 6i
C. 5, -5, 6i, 0
D. -5, -6i
OpenStudy (anonymous):
I got x = 6i
OpenStudy (anonymous):
I solved the last one

Eliminate B and D, as the method I used gives me -5, and 5 so you with your knowledge again of this subject should be able to figure this out.
OpenStudy (anonymous):
So far I've got 6i, 5, and -5.
OpenStudy (anonymous):
So, I'm thinking C.
5, -5, 6i, 0
DivineSolar (divinesolar):
Okay go with your gut feeling or what you believe is right, as I cannot say that is right, all I know is 5 and -5 belong in your answer.
OpenStudy (anonymous):
okay. thank you.

Do you know anything about this one,
what polynomial has a graph that passes through the given points?
(-2, 2) (-1, 1) (1,5) (3, 67)
DivineSolar (divinesolar):
Answer choices?
DivineSolar (divinesolar):
Or word only?

A is incorrect.
OpenStudy (anonymous):
okay
DivineSolar (divinesolar):
B is incorrect.
DivineSolar (divinesolar):
It only passes through 2 points.
DivineSolar (divinesolar):
It may be C as D passes through nothing from what I saw.
