Write a polynomial function of minimum degree with real coefficients whose zeros include those listed. Write the polynomial in standard form. 4, -8, and 2 + 3i
It is good to know that when 2+3i is a zero, then 2-3i is also a zero...
but what do i do with the rest ? i really dont get it
You can now write down the factored form of the polynomial: (x-4)(x+8)(x-2-3i)(x-2+3i) After expanding you have the standard form...
Expanding hint: ((x-2)-3i)((x-2)+3i) is of the form (a-b)(a+b)=a²-b²
