Subproblem 1
Set the factor '(35 + -2s + s2)' equal to zero and attempt to solve:

Simplifying
35 + -2s + s2 = 0

Solving
35 + -2s + s2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-35' to each side of the equation.
35 + -2s + -35 + s2 = 0 + -35

Reorder the terms:
35 + -35 + -2s + s2 = 0 + -35

Combine like terms: 35 + -35 = 0
0 + -2s + s2 = 0 + -35
-2s + s2 = 0 + -35

Combine like terms: 0 + -35 = -35
-2s + s2 = -35

The s term is -2s.  Take half its coefficient (-1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
-2s + 1 + s2 = -35 + 1

Reorder the terms:
1 + -2s + s2 = -35 + 1

Combine like terms: -35 + 1 = -34
1 + -2s + s2 = -34

Factor a perfect square on the left side:
(s + -1)(s + -1) = -34

Can't calculate square root of the right side.
