13 million (13,000,000) in expanded form is:
(1 x 10000000) + (3 x 1000000) + (0 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1)

If you mean y = 5x-13 then in standard form it is 5x-y-13 = 0
13/1 Thirteen in fraction form is 13/1, or26/2, or 39/3...etc. anything that if you divide out on your calculator it answers 13.
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.
