The Def'n of the xintercept is the points where the yvalue is zero. So set y to 0 and solve for x

you have many choices for finding the solution, if you plan to study math beyond algebra 2 learn to factor (but not everything can be factored), learn to use the quadratic formula (works 100% of the time)

Solutions are the same x=8 and x=5/3 I just showed that if you use the quadratic formula or factoring, you will get the same solutions.
