    for long division 5 steps) \(\huge\color{green}{{1:}}\) Divide the first terms \(\huge\color{green}{{2:}}\) multiply(distribute) \(\huge\color{green}{{3:}}\) subtract all terms \(\huge\color{green}{{4:}}\) carry down \(\huge\color{green}{{5:}}\) repeat

    |dw:1443653544436:dw| multiply divisor by 7x^2 so 7x^2(7x^2+X-5) you didn't multiply 7x^2 by x

    do you by chance know the right answer? I used my last try on the homework and it doesn't tell us the correct answer

    wouldn't it be the same but the remainder would be 7x^3 rather than just x^3

    i don't think so there is another mistake |dw:1443653872383:dw| remembber step number 2 you should distribute (7x^2+x-5) by 7x^2

    it's -15 so it would still be -105x^2

    |dw:1443654359577:dw| we should change the sign so it's -7x^2 you should subtract
