quadratic

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
