Question

Please help i have exams tomorrow! List possible zeros using the rational zero theorem. Could i find these by using synthetic division? Is it the same thing? -_- thanks.

Answer 1

Let me show you an example :)

Answer 2

List all of the possible zeros, use synthetic division to test the possible zeros, find an actual zero, and use the actual zero to find all the zeros of x^4-5x^3+20x-16=0

Answer 3

okay well my question is y=x^3-6x^2+6x-18
Thank you for being the first person to help me after i was asking everyone for like half hour! :P

Answer 4

Oh Welcome !!:)

Answer 5

-x^3+6 x^2-6 x+y+18 = 0

Answer 6

y = x ((x-6) x+6)-18

Answer 7

Hope u got some idea?

Answer 8

Thanks this helps, do you think you can help me with my next one? The question is identify the number of zeros or solutions for
f(x)=12x-32x^2+40-x^3
I am working on this one & the question i just asked.
p.s. don't feel like you have to help me, if you r busy :)

Answer 9

Not to worry :)
I will help you :)

Answer 10

x^2 (32 + x) + f[x] == 40 + 12 x

Answer 11

f(x)+x (x (x+32)-12) = 40

Answer 12

Got it?

Answer 13

:( I'm still having trouble with the first question...

Answer 14

Let me know your doubt?

Answer 15

i can't find the right factor for the synthetic division...or maybe i made a mistake.

Answer 16

Yeah, Please make a double check with your steps
