2.A polynomial of degree 3 in x has at most(a) 5 terms(c) 4 terms(b) 3 terms(d) 1 term |

Answer» b...Themean value theoremstates that p/(x) will have 3 roots. However p/(x) will have degree 2 and therefore will have at most 2 roots. So we get a contra- diction, which means p(x) cannot exist. Thus a polynomial of degree 3 has at most three real roots |
