Simplifying x4 + -12x2 + 18 = 0 Reorder the terms: 18 + -12x2 + x4 = 0 Solving 18 + -12x2 + x4 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-18' to each side of the equation. 18 + -12x2 + -18 + x4 = 0 + -18 Reorder the terms: 18 + -18 + -12x2 + x4 = 0 + -18 Combine like terms: 18 + -18 = 0 0 + -12x2 + x4 = 0 + -18 -12x2 + x4 = 0 + -18 Combine like terms: 0 + -18 = -18 -12x2 + x4 = -18 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 = -18 + 36 Reorder the terms: 36 + -12x2 + x4 = -18 + 36 Combine like terms: -18 + 36 = 18 36 + -12x2 + x4 = 18 Factor a perfect square on the left side: (x2 + -6)(x2 + -6) = 18 Calculate the square root of the right side: 4.242640687 Break this problem into two subproblems by setting (x2 + -6) equal to 4.242640687 and -4.242640687.Subproblem 1
x2 + -6 = 4.242640687 Simplifying x2 + -6 = 4.242640687 Reorder the terms: -6 + x2 = 4.242640687 Solving -6 + x2 = 4.242640687 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 = 4.242640687 + 6 Combine like terms: -6 + 6 = 0 0 + x2 = 4.242640687 + 6 x2 = 4.242640687 + 6 Combine like terms: 4.242640687 + 6 = 10.242640687 x2 = 10.242640687 Simplifying x2 = 10.242640687 Take the square root of each side: x = {-3.200412581, 3.200412581}Subproblem 2
