You are given the factored equation  $\left(x+8\right)\left(x-2\right)=0$  . What is the next step to solve for x.

• Set  $x+8=0$  and $x-2=0$  

• Nothing the solution is  $x=8$  and  $x=-2$  

• Multiply  $\left(x+8\right)\left(x-2\right)$  

• Choose  $x+8$  or  $x-2$  and write a musical about them
