Question

Find the zeros of polynomial function and solve polynomials equations.
f(x)=24x^3-64x^2-21x+56

Answer 1

Since this polynomial has 4 terms, factoring by grouping should be the first thing we try here.

So, we have:

`image`

So, we can use ZPP to find out roots:

`image`

So our three roots are:

`x \in \{(8)/(3),(√(56))/(8),-(√(56))/(8)\}`
