$x+7=0\ \ \ \ \ \ \ x-4=0\ \ \ \ \ \ \ \ \left(x+7\right)\left(x-4\right)=0$  
What value(s) of x would make each equation true?

 $x+7=0\ \ \ \ \ \ \ x-4=0\ \ \ \ \ \ \ \ \left(x+7\right)\left(x-4\right)=0$  
How would you know if the value of x that you got satisfies each equation?

 $x+7=0\ \ \ \ \ \ \ x-4=0\ \ \ \ \ \ \ \ \left(x+7\right)\left(x-4\right)=0$  
Compare the solutions of the given equations. What statement can you make?

 $x+7=0\ \ \ \ \ \ \ x-4=0\ \ \ \ \ \ \ \ \left(x+7\right)\left(x-4\right)=0$  
Are the solutions of  $x+7=0\ \ and\ \ \ x-4=0\ \ \ \ \ \$   the same as the solutions of  $\left(x+7\right)\left(x-4\right)=0$  ? Why?

 $x+7=0\ \ \ \ \ \ \ x-4=0\ \ \ \ \ \ \ \ \left(x+7\right)\left(x-4\right)=0$  
How would you interpret the meaning of the equation  $\left(x+7\right)\left(x-4\right)=0$
