Question

Find the zeros of polynomial functions and solve polynomials equations.
f(x)=x^3-64

Answer 1

we are given

`f(x)=x^3-64`

Since, we have to find zeros

so, we can set f(x)=0

and then we can solve for x

`f(x)=x^3-64=0`

`x^3-64=0`

We will add both sides 64

`x^3-64+64=0+64`

`x^3=64`

Take cube root both sides

`\sqrt[3]{x^3} =\sqrt[3]{64}`

`x=4`...........Answer
