Start with the given equation
Factor the left side (note: if you need help with factoring, check out this solver)
Now set each factor equal to zero:
or
or Now solve for x in each case
So our answer is
or
which means that the x-intercepts are
and
Notice if we graph we can see that the roots are and . So this visually verifies our answer.
