Simplifying 2s4 + 12s2 + 8 = 0 Reorder the terms: 8 + 12s2 + 2s4 = 0 Solving 8 + 12s2 + 2s4 = 0 Solving for variable 's'. Factor out the Greatest Common Factor (GCF), '2'. 2(4 + 6s2 + s4) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(4 + 6s2 + s4)' equal to zero and attempt to solve: Simplifying 4 + 6s2 + s4 = 0 Solving 4 + 6s2 + s4 = 0 Begin completing the square. Move the constant term to the right: Add '-4' to each side of the equation. 4 + 6s2 + -4 + s4 = 0 + -4 Reorder the terms: 4 + -4 + 6s2 + s4 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + 6s2 + s4 = 0 + -4 6s2 + s4 = 0 + -4 Combine like terms: 0 + -4 = -4 6s2 + s4 = -4 The s term is 6s2. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6s2 + 9 + s4 = -4 + 9 Reorder the terms: 9 + 6s2 + s4 = -4 + 9 Combine like terms: -4 + 9 = 5 9 + 6s2 + s4 = 5 Factor a perfect square on the left side: (s2 + 3)(s2 + 3) = 5 Calculate the square root of the right side: 2.236067978 Break this problem into two subproblems by setting (s2 + 3) equal to 2.236067978 and -2.236067978.Subproblem 1
s2 + 3 = 2.236067978 Simplifying s2 + 3 = 2.236067978 Reorder the terms: 3 + s2 = 2.236067978 Solving 3 + s2 = 2.236067978 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + s2 = 2.236067978 + -3 Combine like terms: 3 + -3 = 0 0 + s2 = 2.236067978 + -3 s2 = 2.236067978 + -3 Combine like terms: 2.236067978 + -3 = -0.763932022 s2 = -0.763932022 Simplifying s2 = -0.763932022 Reorder the terms: 0.763932022 + s2 = -0.763932022 + 0.763932022 Combine like terms: -0.763932022 + 0.763932022 = 0.000000000 0.763932022 + s2 = 0.000000000 The solution to this equation could not be determined.This subproblem is being ignored because a solution could not be determined.Subproblem 2
s2 + 3 = -2.236067978 Simplifying s2 + 3 = -2.236067978 Reorder the terms: 3 + s2 = -2.236067978 Solving 3 + s2 = -2.236067978 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + s2 = -2.236067978 + -3 Combine like terms: 3 + -3 = 0 0 + s2 = -2.236067978 + -3 s2 = -2.236067978 + -3 Combine like terms: -2.236067978 + -3 = -5.236067978 s2 = -5.236067978 Simplifying s2 = -5.236067978 Reorder the terms: 5.236067978 + s2 = -5.236067978 + 5.236067978 Combine like terms: -5.236067978 + 5.236067978 = 0.000000000 5.236067978 + s2 = 0.000000000 The solution to this equation could not be determined.This subproblem is being ignored because a solution could not be determined.
