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.
