$7x ^{2}+x-15 \sqrt{49x ^{4}+140x ^{3}-163x ^{2}-296x+165}$ ***SQUARE ROOT SYMBOL = DIVISION SYMBOL***

Which one is numerator and which one is denominator?

4. anonymous

really? We have to do long division with it.

5. Nnesha

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

6. Nnesha

|dw:1443652287940:dw| first divide the first terms $\frac{ 49x^2 }{ 7x^2 }=?$

7. anonymous

|dw:1443652623125:dw| @Nnesha is this correct?

8. Nnesha

wait a sec

9. anonymous

I know it's wrong, i tried to enter it in my homework site and it said it's wrong. but if you could please tell me what i did wrong after you finish it that would be great!

10. Nnesha

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

11. anonymous

oh shoot, thanks i'm gonna try to work it out again

12. anonymous

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

13. Nnesha

no i don't know the answer yet

14. anonymous

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

15. Nnesha

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

16. Nnesha

|dw:1443653921380:dw|

17. anonymous

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

18. Nnesha

ah i was about to say there is mistake somewhere

19. Nnesha

thanks

20. anonymous

thanks for the help!

21. Nnesha

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