<p>1) the number of roots a polynomial has can be determined by the highest degree?
i.e. x^3+2x-1 has a total of 3 roots (imaginary and/or real)?
2) have there been questions abt the rational root test?</p>
<p>thanks</p>
<p>(for q1) in otherwords: for an nth degree polynomial, are there “n” roots?</p>
<p>I’m a bit confused by what you’re asking, but I’ll try to answer your questions.
- Yes. The degree of the polynomial = the number of roots. These roots can be real numbers, double roots (though not in the 3rd power), or imaginary roots (in conjugate pairs).
- I’m not exactly sure what this is, but I assume it will not be necessary because you are able to have your graphing calculator figure out the roots for you. If there would happen to be a question about it, I doubt it would difficult, because the process is pretty simple.</p>
<p>thanks thanks</p>
