Subproblem 1
Set the factor '(-10 + x + x2)' equal to zero and attempt to solve:

Simplifying
-10 + x + x2 = 0

Solving
-10 + x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '10' to each side of the equation.
-10 + x + 10 + x2 = 0 + 10

Reorder the terms:
-10 + 10 + x + x2 = 0 + 10

Combine like terms: -10 + 10 = 0
0 + x + x2 = 0 + 10
x + x2 = 0 + 10

Combine like terms: 0 + 10 = 10
x + x2 = 10

The x term is x.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
x + 0.25 + x2 = 10 + 0.25

Reorder the terms:
0.25 + x + x2 = 10 + 0.25

Combine like terms: 10 + 0.25 = 10.25
0.25 + x + x2 = 10.25

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = 10.25
