Once we are done, we have four matrices: A, B, D, and F. And the product of the two complex matrices can be represented by the following equation: Doing the arithmetic, we end up with this: Since i^2 is equal to -1, the expression can be rewritten: ax+b = 0 is the format for one variable equations. Because the equation solver uses a numerical method, it only works with equations with a single variable, but can find multiple values. The option specifies the maximum degree of polynomials for which the solver tries to return explicit solutions. If the input eqn is an expression and not an equation, solve solves the equation eqn == 0.. To solve for a variable other than x, specify that variable instead.For example, solve eqn for b. The best you can do is rewrite to express y as a function of x. (Complex Numbers: Quartic Equations; 25pts).
