Question

possible zeros of
2x^5+3x^3+5x^2-6

Answer 1

possible zeros come from factors of 6

therefore: 1, -1, 2, -2, 3, -3
But mostly, you try 1 and -1 first

Answer 2

how did you get that?

Answer 3

isnt it factor of 6 and 2?

Answer 4

That is a fact. Possible zeroes come from factors of the coefficient independent of x

Answer 5

Use the remainder theory to find the zeroes for the polynomial

Answer 6

if P(x) = 0, x is a zero.

Answer 7

well think you can find it or me for now?

Answer 8

Find it yourself I just told you how to find it

Answer 9

lol im on a test bro..

Answer 10

2x^5+3x^3+5x^2-6 = 0

No of possible for Real Positive roots is 1

no of possible for Real -ve roots is 2 or 0

Answer 11

since f(0)<0 and f(1)>0 one root is between 0 and 1

Answer 12

Bolzano theorem

Answer 13

i have to use the rational zeros theorem

Answer 14

root is 0.83271 it is not integer, so it is not easy
