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
That is correct! Thank you!
