If a,b,c,d, and e are real numbers and a≠0, then the equation of
A. No Real Roots
B. At least One Real Root
C. An Odd number of non-real Roots
D. Only One Real Root
E. No Positive Real Roots.
I understand the basic concept of roots, where x is a number such that f(x)=0, but how would you apply that to this problem?
