    Answer:

    When adding polynomials you’ve got to combine all like terms

    2u^3 + 7u^3= 9u^3 (They both are raised to the third with the same variable.)

    6u^2 (Stays the same because there are no other numbers that are raised to the second)

    -7u (Again there are no other numbers to combine this with)

    2+4=6 (Add 2+4 as normal)

    Now you put together all the numbers that are left for your final answer

    9u^3+6u^2-7u+6

    Hope this helps 😉
