hey /sci/, first time poster, here's an interesting set of questions
not my homework, just some bonuses on my last precalculus test i was intrigued by.
first is (oh and x^y means x to the y power);
what do you get when you divide x^74-5x^60+x^23+x^6 by x-2?
this one i'm stumped on, you would have to write out all the intermediate x values with a zero coefficient, right?
last one was: write a polynomial with the roots (4, 5, i2). I know the 4 and 5 would be (x-5) and (x-4), but what about that i2? how would you work BACKWARDS through the quadratic formula?
