## monroemoemoe 3 years ago Determine the solution set of x2 - 80 = 0

1. monroemoemoe

do i solve this by saying 80*80

2. Mimi_x3

is it \(x^2 - 80 =0\)

3. monroemoemoe

yes

4. Mimi_x3

do you konw that you're solving for \(x\)?

5. monroemoemoe

I Have to find the square root

6. Mimi_x3

no the \(x\) lets go slowly

7. Mimi_x3

\(x^2 - 80 = 0\) \(x^2 = 80\)

8. Mimi_x3

do yo understand? when you move it to the other side its a positive?

9. monroemoemoe

yes i understand

10. Mimi_x3

then when its squared you remove it to the other side its sqrt

11. Mimi_x3

i mean move**

12. monroemoemoe

so i do 80 times 80

13. Mimi_x3

\[x^2 = 80\] show me what you would to solve for x

14. monroemoemoe

im not sure if i square 80 or find the factors of 80

15. Mimi_x3

why would you square it? its sqrt(80) when you move it to the left hand side

16. monroemoemoe

what is sqrt

17. Mimi_x3

square root

18. monroemoemoe

so do i find the factors of it then

19. Mimi_x3

why would you want tol find find factors you are just solving for \(x\)!!!

20. monroemoemoe

o well im jus not understanding thats why im asking becasue i don't know my next steps

21. Mimi_x3

show me what you did after x^2 =80 in this question you are basically solving for a varaible i.e. x

22. monroemoemoe

i dont know thats why im here to get this explained to me so i can do it by myself

23. Mimi_x3

okay i just told you!! the right hand side is x^2 then the left hand side is squareroot

24. monroemoemoe

thank you
