Question

find the complex zeros of x^3+27. write f in factored form

Answer 1

\[\Large f(\color{red}x) =\color{red}x^3 + 27 \]

Answer 2

Any idea how to start?

Answer 3

you function is the sum of 2 cubes and it can be factored by using

\[a^3 + b^3 = (a +b)(a^2 - ab + b^2)\]

you need to work out what a and b are in your problem

the complex roots occur in the quadratic, so use the general quadratic formula to find them.
