Today JPaul and I took notes on 1.5, regarding radicals with negatives, and rationalizing complex numbers. First we discussed how to factor out a negative root by making it imaginary. Then we used radical properties to combine terms. JPaul did well with this section. He is good at doing calculations in his head. However, I encourage him to write out the steps so in the event he makes a mistake, we can retrace his steps to find the error. Lastly, we covered rationalization of complex numbers. We discussed how it's considered improper to leave i's in the denominator. So to clear them, we must multiply by the conjugate to rationalize them.
