Find all values of $x$ such that $x^2-5x + 4=0$. If you find more than one value, then list your solutions in increasing order, separated by commas.

x^2 - 5x + 4  =  0     factor as

 

(x - 4) ( x - 1)  = 0

 

Set  both factors to 0 and solve for x

 

x  - 4  = 0          x  - 1  = 0

x  = 4                   x  = 1

 

So

 

x  = 1, 4
