Find all values of x such that x2 – 5x + 4 = 0.  If you find more than one value, then list your solutions, separated by commas.  

 

                                                   x2 – 5x + 4 = 0  

This is a quadratic equation,  

and an easy one, too.  

 

It factors to                                   (x – 1)(x – 4) = 0   

 

Therefore, the values of x are       x = 1  &  x = 4
