Simplifying f(x) = 1 + -1Ix + -2I Multiply f * x fx = 1 + -1Ix + -2I Reorder the terms: fx = 1 + -2I + -1xI Solving fx = 1 + -2I + -1xI Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by 'x'. f = x-1 + -2x-1I + -1I Simplifying f = x-1 + -2x-1I + -1I Reorder the terms: f = -1I + x-1 + -2x-1I
