do you konw that you're solving for \(x\)?
anonymous
  • anonymous
I Have to find the square root
Mimi_x3
  • Mimi_x3
no the \(x\) lets go slowly
Mimi_x3
  • Mimi_x3
\(x^2 - 80 = 0\) \(x^2 = 80\)
Mimi_x3
  • Mimi_x3
do yo understand? when you move it to the other side its a positive?
anonymous
  • anonymous
yes i understand
Mimi_x3
  • Mimi_x3
then when its squared you remove it to the other side its sqrt
Mimi_x3
  • Mimi_x3
i mean move**
anonymous
  • anonymous
so i do 80 times 80
Mimi_x3
  • Mimi_x3
\[x^2 = 80\] show me what you would to solve for x
anonymous
  • anonymous
im not sure if i square 80 or find the factors of 80
Mimi_x3
  • Mimi_x3
why would you square it? its sqrt(80) when you move it to the left hand side
anonymous
  • anonymous
what is sqrt
Mimi_x3
  • Mimi_x3
square root
anonymous
  • anonymous
so do i find the factors of it then
Mimi_x3
  • Mimi_x3
why would you want tol find find factors you are just solving for \(x\)!!!
anonymous
  • anonymous
o well im jus not understanding thats why im asking becasue i don't know my next steps
Mimi_x3
  • Mimi_x3
show me what you did after x^2 =80 in this question you are basically solving for a varaible i.e. x
anonymous
  • anonymous
i dont know thats why im here to get this explained to me so i can do it by myself
Mimi_x3
  • Mimi_x3
okay i just told you!! the right hand side is x^2 then the left hand side is squareroot
