10. Find all the zeroes of the equation. –3x4+ 27x2 + 1200 = 0 (2 points)
can somone help plzz
i dont get this i need help now pleaz
All of the terms can be divided by -3, and then treated as a quadratic.
can u show me step by step how im kinda confused pleaz
What do you get after dividing all the terms by -3?
-1x^4-8x^2+400=0
i think i did it wrong
Yeah, that's not quite it. \(\large –3x^4+ 27x^2 + 1200 = 0 ÷ -3 \rightarrow x^4-9x^2 -400 = 0 \)
Now make a substitution of y=x^2
i dont get what ur talking about could u be more spisi
pleaz
No, it is not possible for me to be more specific. I told you exactly what you need to do. Once you have it in quadratic form, you may factor it.
i seriously dont get these pleaz help
If you had the equation y^2−9y−400=0, would you be able to solve it?
nop
wait yes i would
Can you help me I dont understand how to do it at all :/
i still did not get it
Dang, I'm 14 lessons behind and I'm failing :/ I'm trying to get caught up and passing so I wont fail the semester
@KenaRolin same here :(
@KenaRolin @Natalovesya Samee :c But, I'm 27 days behind
in Algebra 2, right? Cuz I'm 19 lessons behind in math :(
Yeess, maybe you could help me catch up and then I could help you with the rest? Or any other class we might have together? I finished with most of mine except math
Yeah same. ok! what lesson are you on? And what other classes do you have?
Unit 5 Lesson 9. I have 3D Art Modeling, Biology, English 11, Psychology, and US History
@Natalovesya Nevermind, I'm on the Unit 5 Test now. If you have done it, it would be GREAT if you could please, help me out. Thanks xx
We have a loot of the same classes :) I also have Biology, Psychology, and US History
Unit 5 Test? Isn't that after the Unit Portfolio? Cuz, I'm stuck on that :(
