Answer:

The x-intercepts are (-6,0) and (4,0).

Explanation:

To find the x-intercepts, find the roots of the function by factoring the quadratic or using the quadratic formula. This expression is factorable so find two number which multiply to -24 and add to 2. These are 6 and -4.

Write them as (x+6)(x-4) =0.

Set each one equal to 0 and solve for x.

x+6=0 so x=-6

x-4=0 so x=4

The x-intercepts are (-6,0) and (4,0).
