Question

I really need help with this question. Thanks! Find the zeros of the function algebraically. Be sure to show all work.


f(x)=x^2-8x+15
---------------
10x

Answer 1

First factor x^2-8x+15


You should get

(x-5)(x-3)

Now set each factor equal to zero and solve for x

x-5=0

x-3=0

Answer 2

@Mia, did I do this write?

x^2-8x+15
(x + 3) (x + 5)
x-5=0 x-3=0

The zeros would be x = 3 x = 5

Answer 3

Yes
