I don't understand how to write in standard form. My teacher hasn't taught this yet so I am very confused. Please help and show work. Thanks!

First one.....we write  the terms in descending powers of   m......so we have

4m^3 - 9 m^2 - m + 25     (cubic polynomial)

Second one  ...... same thing ....descending powers of k  ....so we have

(3/4)k^5  - (1/2)k^3       (quintic polynomial)

Third one.....this is a polynomial  in two variables

The form is     ax^2 + bxy + cy^2 + dx + ey + f

So we have

-x ^2   -3xy  + 14y^2    (second power polynomial)

Last one.....nothing to be done.....there's no other way to write 9x  ( first degree polynomial )
