Question

Find only the rational roots of x4 – 9x3 + 16x2 + 18x – 36 = 0.

x = –6, x = 3

x = 6, x = 3

x = –6, x = –3

x = 6, x = –3
I think it is b

Answer 1

@Michele_Laino

Answer 2

is b right

Answer 3

yes! I confirm option B

Answer 4

ok and is this false The possible rational roots of x3 + 3x2 – 4x + 2 are +/- 3 and +/- 2.

True

False

Answer 5

yes! I confirm, it is false, since the rational roots have to be searched among the divisors of the quotient \(2/1=2\)

Answer 6

ok thanks so much!
