## anonymous 5 years ago Just would like to make sure my answer for this quadratic expression is correct!

1. anonymous

$x ^{2}-8x+16=0$

2. anonymous

(x -4)^2=0 x=4, 4

3. anonymous

x=4

4. anonymous

and so far I have, $x=8 + or - \sqrt{64-64}\over 2$ I know the 64s can cancel..but what will my answer look like from here?

5. anonymous

there are two solutions for this one 4 and 4

6. anonymous

ohh so theres one solution? just 4

7. anonymous

no..two

8. anonymous

ha, sorry i keep typing after you answer my ?

9. anonymous

10. anonymous

could be real or complex

11. anonymous

4 is 4 so you would only write it once if you were solving by factoring or quadratic formula

12. anonymous

ok. this is an online assignment I have to submit so i'd like to get the formula right. I should just put 4 under the 1 solution?

13. anonymous

we use the quadratic formula...when u can't factorize or it is hard to guess...but here 4 and 4 add up to 8 and gives the product 16.

14. anonymous

there r two solutions.. 4 and 4

15. anonymous

ok thanks.. It just seems strange putting only the 4 in as 2 different answers. They are both real solutions?

16. anonymous

is it multiple choice

17. anonymous

yes they are both real obviously....but dont forget to write it twice otherwise teacher might think u got only one root..

18. anonymous

no, I select whether there are 2 different real solutions, 2 non real solutions or 1 solution

19. anonymous

ok then ...all good

20. anonymous

fan me if u liked my help..thanx

21. anonymous

2 real solutions

22. anonymous

did you enter it in

23. anonymous

It's online so it's picky with the format. Do I have this in a root?

24. anonymous

no i haven't yet. I will in a sec

25. anonymous

it says two DIFFERENT solutions, I still think it is one solution even if is a quad bc 4 is distinct

26. anonymous

i just realized it says one repeated real solution..so maybe i should put it under that category?

27. anonymous

I think so to, i'll find out!

28. anonymous

yes......

29. anonymous

YES!!!!!

30. anonymous

yep, that was correct. Sorry, my fault I didn't specify that. Thanks for your help guys!

I knew something wasn't right...you're welcome...fan me please
