Best ResponseYou've already chosen the best response.2Very good! so far, you have figured out that "0" is a zero with a multiplicity of "4"

Best ResponseYou've already chosen the best response.2yes. so im having trouble doing the other one so do i do the quadratic formula ? bc its going to give me i

Best ResponseYou've already chosen the best response.2ofcourse yes, quadratic formula is always there for quadratic polynomials, use it..

Best ResponseYou've already chosen the best response.2but wait a moment, you could also tell a lot about zeroes from the sign of discriminant

Best ResponseYou've already chosen the best response.2Look at only the quadratic polynomial : \(x^23x+9\) whats the value of its discriminant ?

Best ResponseYou've already chosen the best response.0this is easy if you know how to use synthetic division after you find a factor of the equation. Just giving you a side note :)

Best ResponseYou've already chosen the best response.2discriminant is just 27, what does that tell you about the roots ?

marcelie

Best ResponseYou've already chosen the best response.2can synthetic be possible too ?

Best ResponseYou've already chosen the best response.2negative discriminant tells you that the roots are not real

Best ResponseYou've already chosen the best response.1I'm thinking: 0 is a root of multiplicity 4 3/2  ( (3i * sqrt(3) ) /2 is a root of multiplicity 1 3/2 + ( (3i * sqrt(3) ) /2 is a root of multiplicity 1

Best ResponseYou've already chosen the best response.2sumone please help me .. im so lost DX

Best ResponseYou've already chosen the best response.1If 3 multiplicity of 2, then the original equation should have been \(\large\rm 2x^6\color{red}{12}x^5+18x^4\) Are you sure you wrote it down correctly? :o

Best ResponseYou've already chosen the best response.2yes. :( let me show you the problem. please dont leave me hanging lol

Best ResponseYou've already chosen the best response.2so idk .. if i factored out wrong or the paper is wrong

Best ResponseYou've already chosen the best response.1ya your work looks fine :o https://www.wolframalpha.com/input/?i=roots+of+2x%5E66x%5E5%2B18x%5E4 wolfram confirms the roots also.

Best ResponseYou've already chosen the best response.1I think you're doing something silly, like not looking at the correct answer key or something >.>

Best ResponseYou've already chosen the best response.2z. lol answer is 0 with multiplicity 4, 3 with multiplicity 2

marcelie

Best ResponseYou've already chosen the best response.2how the hell they get 3 wit multi 4 ?

Best ResponseYou've already chosen the best response.13 with multiplicity 2? I dunno, they're being silly billies. Books make mistakes sometimes.

Best ResponseYou've already chosen the best response.2so how do i graph it since i have i 's

marcelie

Best ResponseYou've already chosen the best response.2second equation gives me  as answer so that cant b taken its a neg right ?

Best ResponseYou've already chosen the best response.1oh you have to graph it now? :o interesting

Best ResponseYou've already chosen the best response.1@zepdrix posted the graph as part of the Wolfram work https://www.wolframalpha.com/input/?i=roots+of+2x^66x^5%2B18x^4 It looks like a flat nose parabola but the graph is not a parabola. More of a Ushape.

Best ResponseYou've already chosen the best response.2so yall think my book is wrong

Best ResponseYou've already chosen the best response.1ya, definitely :o they made a typo in the function, it shoulda been 12 on the x^5. It looks like they wanted you to determine the multiplicity based on the graph, not based on factoring, isn't that what it says? :D so maybe use a graphing calculator?

Best ResponseYou've already chosen the best response.1Yes, I do. Email the teacher to discuss it. You should not lose points because of someone's typo and lack of proof reading skills.
