The given quadratic is 2x² - 5x + 2.

The first term, 2x², has factors 2x and x.

The last term, 2, factors as (1)^.(2), as (-1)^.(-2), as (2)^.(1), or as (-2)^.(-1). Trying the first gives

(2x + 1)(x + 2) = 2x² + 5x + 12. No good, but almost right except for the sign of the coefficient of x.

The second gives

(2x - 1)(x - 2) = 2x² - 5x + 2. Correct!

Enter this as (2*x-1)*(x-2)
