Ryann Burch · Answer 1

2x-6x+5=0

-4x+5=0

-4x=-5

Paloma Bowman · Answer 2

Let's factor first:

x^2 - 6x + 5 = 0

Take factors of 5 that add to - 6. In this case, - 5 and - 1.

These will be used in your binomials:

(x - 5) (x - 1) = 0

Solve each value:

x - 5 = 0

x = 5

x - 1 = 0

x = 1

The largest x is equal to 5.
