Subproblem 1

Set the factor 'cesx' equal to zero and attempt to solve: Simplifying cesx = 0 Solving cesx = 0 Move all terms containing c to the left, all other terms to the right. Simplifying cesx = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(2 + c2)' equal to zero and attempt to solve: Simplifying 2 + c2 = 0 Solving 2 + c2 = 0 Move all terms containing c to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + c2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + c2 = 0 + -2 c2 = 0 + -2 Combine like terms: 0 + -2 = -2 c2 = -2 Simplifying c2 = -2 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 3

Set the factor '(-2 + c2)' equal to zero and attempt to solve: Simplifying -2 + c2 = 0 Solving -2 + c2 = 0 Move all terms containing c to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + c2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + c2 = 0 + 2 c2 = 0 + 2 Combine like terms: 0 + 2 = 2 c2 = 2 Simplifying c2 = 2 Take the square root of each side: c = {-1.414213562, 1.414213562}

Solution

c = {-1.414213562, 1.414213562}
