Mica is solving for the zeros of a quadratic function by

completing the square. Her work is shown. What error

did Mica make?

-Mica 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.
