Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(100 + 2x + x2)' equal to zero and attempt to solve: Simplifying 100 + 2x + x2 = 0 Solving 100 + 2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-100' to each side of the equation. 100 + 2x + -100 + x2 = 0 + -100 Reorder the terms: 100 + -100 + 2x + x2 = 0 + -100 Combine like terms: 100 + -100 = 0 0 + 2x + x2 = 0 + -100 2x + x2 = 0 + -100 Combine like terms: 0 + -100 = -100 2x + x2 = -100 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = -100 + 1 Reorder the terms: 1 + 2x + x2 = -100 + 1 Combine like terms: -100 + 1 = -99 1 + 2x + x2 = -99 Factor a perfect square on the left side: (x + 1)(x + 1) = -99 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
