Find all the solutions of the equation p(x) = 0 if
p(x) = 3(x)^4 + 5(x)^3 + 25(x)^2 + 45x - 18
and 3i is one of the solutions.
Find all the solutions of: . if is one of the solutions.
If is a solution, then is also a solution.
. . Complex roots appear in conjugate pairs.
Then is a factor of the polynomial.
Using long division, we have: .
. . which factors further: .
Therefore, the roots are: .
