Simplifying x4 + -12x2 + 16 = 0 Reorder the terms: 16 + -12x2 + x4 = 0 Solving 16 + -12x2 + x4 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-16' to each side of the equation. 16 + -12x2 + -16 + x4 = 0 + -16 Reorder the terms: 16 + -16 + -12x2 + x4 = 0 + -16 Combine like terms: 16 + -16 = 0 0 + -12x2 + x4 = 0 + -16 -12x2 + x4 = 0 + -16 Combine like terms: 0 + -16 = -16 -12x2 + x4 = -16 The x term is -12x2. Take half its coefficient (-6). Square it (36) and add it to both sides. Add '36' to each side of the equation. -12x2 + 36 + x4 = -16 + 36 Reorder the terms: 36 + -12x2 + x4 = -16 + 36 Combine like terms: -16 + 36 = 20 36 + -12x2 + x4 = 20 Factor a perfect square on the left side: (x2 + -6)(x2 + -6) = 20 Calculate the square root of the right side: 4.472135955 Break this problem into two subproblems by setting (x2 + -6) equal to 4.472135955 and -4.472135955.Subproblem 1
x2 + -6 = 4.472135955 Simplifying x2 + -6 = 4.472135955 Reorder the terms: -6 + x2 = 4.472135955 Solving -6 + x2 = 4.472135955 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + x2 = 4.472135955 + 6 Combine like terms: -6 + 6 = 0 0 + x2 = 4.472135955 + 6 x2 = 4.472135955 + 6 Combine like terms: 4.472135955 + 6 = 10.472135955 x2 = 10.472135955 Simplifying x2 = 10.472135955 Take the square root of each side: x = {-3.236067978, 3.236067978}Subproblem 2
