Write a polynomial function with rational coefficients so that p(x)=0 has the given roots.

explain how you did it too.
because i'm confused.

2i and 1
2 + i and -4

5\16 x 2\5 = 10/80simplify to 1/80

The answer would he -4,-2 because the points are just on the opposite side. since the x axis is +4 it's going to he -4 and since the y axis is -2 it stays there because whaen rotated it stays in the third quadrant
