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  the left side as  :

 

(x - 1) ( x - 4)  = 0

 

Set both factors to 0   and solve for x and we have that   x  = 1, 4
