If you were to write 7/28 in its simplest form then it would just be 1/4.
4/28 = 1/7
To have a zero at 2, you need to include a factor (x - 2). To have a zero at 13 + i, you need a factor (x - (13 + i)). To have real coefficients, for each non-real factor you need to include its complex conjugate, so in this case, (x + 13 + i).Thus, you have the factors: (x - 2)(x - (13 + i))(x + 13 + i) You can multiply the factors together to get the polynomial into standard form. I suggest you start with the complex conjugates, that makes it easier.
The square root of 28 or in this case the radical form of 28 will be 2 times radical 7. Since 28 is 4 times 7 and the square root of 4 is two.
