Long Way First set the equation equal to zero. Then multiply both sides by the denominator. Next solve then you get the x-intercepts
Get the numerator and set it to zero. Then solve and you get the x-intercept.

Unit G Summary Question #9 X-Intercept
9. Describe how to find the x-intercepts of a rational function. Include both the long way and the shortcut way, explaining why the shortcut makes mathematical sense.
Long Way
First set the equation equal to zero. Then multiply both sides by the denominator. Next solve then you get the x-intercepts
Short Way
Get the numerator and set it to zero. Then solve and you get the x-intercept.
