f(x) = 2x2 – 4x – 30 = 2x2 – 4x – 33 = 2(x2 – 2x)3 + 1 = 2(x2 – 2x + 1)4 = 2(x – 1)22 = (x – 1)2± = x – 11 ± = x Mica is solving for the zeros of a quadratic function by completing the square. Her work is shown. What error did Mica make?ANSWER CHOICESMica should have set each x = 0 instead of f(x).Mica should have added 2 to 3 instead of 1.Mica should have multiplied both sides by 2 instead of dividing.Mica should have subtracted 1 from both sides instead of adding.
