Question

Find all possible rational roots of:

Answer 1

\[f(x) = 2x^3 -3x^2 - 18x - 8\]

Answer 2

so start by listing all the factors of the constant p (-8) including the +/- sign
list the factors of the coefficient q (2) including the +/- sign

then all the rational roots are just every single combination of p/q

Answer 3

Yeah, in my notes I had p and q switched, so I was stuck wondering where I was getting the numbers from ._.

Answer 4

Thank you, I got this now
