${x}^{2}-25=0$

$\left( x-5 \right) \times \left( x+5 \right)=0$

$\begin{array} { l }x-5=0,\\x+5=0\end{array}$

$\begin{array} { l }x=5,\\x+5=0\end{array}$

$\begin{array} { l }x=5,\\x=-5\end{array}$

$\begin{array} { l }x_1=-5,& x_2=5\end{array}$

User One of the applications of the derivative of a function is its use in Physics, where a function that at every instant t associates the number s(t), this function s is called the clockwise function of the movement. By deriving the time function we obtain the velocity function at time t, denoted by v(t). A body has a time function that determines its position in meters at time t as S(t)=t.³√t+2.t . Present the speed of this body at time t = 8 s.
