seem to be needed along with synthetic division ... but I have no clue how to apply them. Here's an example of what I need to know how to do for my online precalculus class:
State how many imaginary and real zeros the function has.
f(x) = x^3 - 20x^2 + 123x - 216
ve a clue at how to do it.
Take 2mL of the NaHSO3 solution. Add a drop of dilute HCl solution then add .02M KMnO4 solution one drop at a time, mixing after each drop, up to no more than 5 drops. What changes did you see? Test for SO42- by adding .1MBaCl2 solution one drop at a time, mixing after each drop, up to 6 drops. Write the balanced half-reaction equation for the oxidation of the bisulfite ion, HSO3-.
