Question

Use the Rational Zeros Theorem to write a list of all possible rational zeros of the function.

f(x) = -2x⁴ + 4x³ + 3x² + 18

Answer 1

find all the factors of the constant 18 call then p

and then find all the factors of the coefficient of the leading term - 2 and call them q

the list of possible rational roots will be p/q

so you would need to list for example

18/2 and 18/-2 which simplifies to 9 and -9

so there are 6 more

hope it helps

Answer 2

Thank you!!
