Can someone help me on solving for real, complex, irrational, and imaginary zeros? Thank you for the help!

Y = (x/100)(x - 10)(x - 15) [ (1/2)x - 1)] [ (1/4)x - 2 ] ^2

 

If you are setting this to  0......the roots are easy to find since it's already in factored form

 

We just set  each factor to  0    and we have

 

(x / 100)  = 0    →  x = 0    is a root

 

(x - 10) = 0     →  x = 10 is a root

 

(x - 15)  = 0  →   x = 15 is a root

 

[(1/2)x  -1 ]   = 0    →   (1/2)x  = 1   →  x = 2  is a root

 

( [1/4 ] x   -  2)^2 →  (1/4)x  - 2  = 0   →  (1/4)x  = 2 →   x = 8  is a root

 

So....the roots are    0, 2, 8, 10, 15     and they are all real
