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

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

So, we have:

So, we can use ZPP to find out roots:

So our three roots are:

35%

step-by-step explanation:

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
