Question

What are the zeros of the function? What are there multiplicities? f(x)=4x^3-20x^2+24X

Answer 1

you can factor out of 4x.

Answer 2

how do I do that

Answer 3

\(\large\color{black}{ f(x)=4x^3-20x^2+24x }\)
set f(x)=0

\(\large\color{black}{ 0=4x^3-20x^2+24x }\)

and you can see that all terms on the right side of the equation have 4x in common, right?
So take the 4x out.

Answer 4

so is the answer \[-20x^2+24x\]
