Answer:
There is one real solution (and 2 complex conjugate solutions)
Step-by-step explanation:
The discriminant of x³ + px + q is -4p³-27q².
So the discriminant of x³ - 3x + 4 is
-4×(-3)³ - 27×4² = 108 - 432 = -324.
As this is negative (and the coefficients are real), there is just one real solution.
The other two solutions are therefore complex conjugates.
