Question

How do you find all the zeros of `f(x)=4x(x-4)(x+12)(x-1/2)`?

Answer 1

`x = 0, or 4, or -12, or 1/2`

Explanation:

Since `f(x)` has been factorized in the question any of it's factors set to zero will result in `f(x) = 0`

Hence the zeros of `f(x)` are:

Either `4x = 0 -> x = 0`
Or `x-4 = 0 -> x =4`
Or `x+12 = 0 -> x=-12`
Or `x-1/2 = 0 -> x=1/2`
