    no the \(x\) lets go slowly

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

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

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

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

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

    so do i find the factors of it then

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