The zeros are x=5 and x=3

Step-by-step explanation:

x^2-8x+15

To find the zeros, we set the equation equal to zero

x^2-8x+15 = 0

Factor the equation

What 2 numbers multiply to 15 and add to - 8

-5*-3 = 15

-5+-3 = - 8

(x-5) (x-3) = 0

Using the zero product property

x-5 = 0 x-3 = 0

x=5 x=3

The zeros are x=5 and x=3
