...factor completely
intercepts for this are:
=>
and =>
To find the intercepts for each of the following
a)
b)
c)
simply substitute the new values
a)
or and or
b)
or and or
c)
or and or
you can also do it this way:
a)
set to zero to find the x-intercepts
...........both sides divide by
...........factor
if =>
if =>
the x-intercepts are and
same way you can do b) and c)
