Subproblem 1
Set the factor '(1 + -5x + 2x2)' equal to zero and attempt to solve:

Simplifying
1 + -5x + 2x2 = 0

Solving
1 + -5x + 2x2 = 0

Begin completing the square.  Divide all terms by
2 the coefficient of the squared term: 

Divide each side by '2'.
0.5 + -2.5x + x2 = 0

Move the constant term to the right:

Add '-0.5' to each side of the equation.
0.5 + -2.5x + -0.5 + x2 = 0 + -0.5

Reorder the terms:
0.5 + -0.5 + -2.5x + x2 = 0 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + -2.5x + x2 = 0 + -0.5
-2.5x + x2 = 0 + -0.5

Combine like terms: 0 + -0.5 = -0.5
-2.5x + x2 = -0.5

The x term is -2.5x.  Take half its coefficient (-1.25).
Square it (1.5625) and add it to both sides.

Add '1.5625' to each side of the equation.
-2.5x + 1.5625 + x2 = -0.5 + 1.5625

Reorder the terms:
1.5625 + -2.5x + x2 = -0.5 + 1.5625

Combine like terms: -0.5 + 1.5625 = 1.0625
1.5625 + -2.5x + x2 = 1.0625

Factor a perfect square on the left side:
(x + -1.25)(x + -1.25) = 1.0625

Calculate the square root of the right side: 1.030776406

Break this problem into two subproblems by setting 
(x + -1.25) equal to 1.030776406 and -1.030776406.

Simplifying
x + -1.25 = 1.030776406

Reorder the terms:
-1.25 + x = 1.030776406

Solving
-1.25 + x = 1.030776406

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '1.25' to each side of the equation.
-1.25 + 1.25 + x = 1.030776406 + 1.25

Combine like terms: -1.25 + 1.25 = 0.00
0.00 + x = 1.030776406 + 1.25
x = 1.030776406 + 1.25

Combine like terms: 1.030776406 + 1.25 = 2.280776406
x = 2.280776406
