Form a polynomial f(x) with real coefficients having the given degree and zeros. degree 5; zeros: -1; −i; −7+i

Bearing in mind that complex roots, do not come all by their lonesome, the zeros of "-i" or "0-i"   and "-7+i" aren't here all by themselves, they came with their sister, the conjugate

so, that is 0-i also comes with 0+i
and -7+i also comes with -7-i

so, the zeros, or solutions or roots, are 

so, their product, is the 5th degree polynomial
