The x intercepts are the points where y=0. So set y equal to zero in the equation and solve for x:
Factor this to get your values of x:
So now you have 2 factors, (x+5) and (x-3). Since their product is equal to zero, each individual factor can be equated to zero. Then, it is easy to solve for x:
Good Luck,
