X^3+2x^2+3x+4=0 why the value of x is complex number?
I have a question about a math problem. Can you help me understand why the value of x is a complex number in the equation X^3+2x^2+3x+4=0?
Sure, I'll try my best to help explain it. When solving this polynomial equation, we can use the rational root theorem to look for potential rational roots. However, we see that there are no rational roots, so we know that the solutions will be complex numbers.
