-5 and 3 will be because for -5 it is (-5,0) and 3 is (3,0)
Explanation:
Answer:
x=3 and x=-5
To find the x intercepts set y =0 and solve for x
0 = x^2+2x-15
Factor
What two numbers multiply to -15 and add to 2
5*-3 = -15
5+-3 =2
0 = (x+5) (x-3)
Using the zero product property
x+5=0 x-3 =0
x=-5 x=3
