Step-by-step explanation:
Biquadratic Equation
It's a fourth-degree equation where the terms of degree 1 and 3 are missing. It can be solved for the variable squared as if it was a second-degree equation, and then take the square root of the results
Our equation is
If we call , our equation becomes a second-degree equation
Dividing by -3
Factoring
It leads to these solutions
Taking back the change of variable, we have for the first solution
Now for the second solution, we get imaginary (complex) values
Summarizing, the four solutions for x are
