WebUse the Quadratic Formula: x = − (−4) ± √ (−9) 2 √ (−9) = 3 i (where i is the imaginary number √−1) So: x = 4 ± 3i 2 Answer: x = 2 ± 1.5 i The graph does not cross the x-axis. That is why we ended up with complex numbers. BUT an upside-down mirror image of our equation does cross the x-axis at 2 ± 1.5 (note: missing the i ). WebMar 24, 2024 · A quartic equation is a fourth-order polynomial equation of the form z^4+a_3z^3+a_2z^2+a_1z+a_0=0. (1) While some authors (Beyer 1987b, p. 34) use the term "biquadratic equation" as a synonym for quartic equation, others (Hazewinkel 1988, Gellert et al. 1989) reserve the term for a quartic equation having no cubic term, i.e., a quadratic … WebStep 1: Enter the equation you want to solve using the quadratic formula.
