Question

Use the Rational Root Theorem to list all possible rational roots of the polynomial equation x3 - 4x2 + 7x - 8 = 0. Do not find the actual roots.

A. –8, –1, 1, 8

B. –8, –4, –2, –1, 1, 2, 4, 8

C. 1, 2, 4, 8

D. no possible roots

Answer 1

i think its D not sure tho

Answer 2

possible rational zeros of g(x)=x3-4x2+x-10 using the rational zero theorem? ... [ possible rational roots of the following equation:3x^4 + 5x^3 + 3x^2 - 7x + 9 = 0

Answer 3

so would the answer be B

Answer 4

ya

Answer 5

can 1 be the root of that equation ? :)

Answer 6

yes

Answer 7

if you sub x = 1 into the equation : x^3 - 4x^2 + 7x - 8 = 0, do you have both side equal ?

Answer 8

i dont think so

Answer 9

isn't A, B, C all have 1 in it ? :)

Answer 10

yes
