If given a quadratic equation with the complex number, z, as the variable, and the solution is something like 3+-root(4)
Does that mean z = 3 + root(4)i, 3 - root(4)i. Or does that mean z = 3-root(4), 3+root(4) (i.e. no imaginary term)
REASON: I did a question whereby if you replace z = x + iy, then x = 3, y = +- (root4). But if doing the way which leads to the quadratic formula, you don't get an imaginary term within it
