Answer by MathLover1(20850) (Show Source): You can put this solution on YOUR website!
a.
......set and factor completely
solutions:
if =>
if =>
if =>
so, here you have three real zeros
see it on a graph:
b.
solutions:
if =>=> one real solution
if ...use quadratic formula
so, you have two imaginary zeros
and
