Math add the polynomials

(7ab+4a2b4)+(a2b4-7ab)


The 2 and 4 are on top of the a and b. (sqare #)

  • Math add the polynomials -

    You need to find the like terms, for example, a²b4 and 4a²b4 are like terms.
    You can add them together to make 5a²b4.
    So
    a²b4+4a²b4=5a²b4

    Like terms must have the same variables each raised to the same power. We can add like terms by adding the coefficients, as we did above.

    ahh so the 7ab cancels because of the -7ab so answer is 5a²b4. I thought it was 4a4b8


    Thank you

  • Math add the polynomials -

    yes 7 a b - 7 a b = 0
    and the answer is
    5 a^2 b^4

  • To Adriana: -

    Your answer is correct.

  • Math add the polynomials -

    so its 4a^2b^8?

  • Math add the polynomials -

    I mean this is correct:
    "ahh so the 7ab cancels because of the -7ab so answer is 5a²b4."

  • Math add the polynomials -

    Post it.

  • Math add the polynomials -

    "...so answer is 5a²b4"
