Simplifying x4 + -1 + 15 = 14x2 + -14 Reorder the terms: -1 + 15 + x4 = 14x2 + -14 Combine like terms: -1 + 15 = 14 14 + x4 = 14x2 + -14 Reorder the terms: 14 + x4 = -14 + 14x2 Solving 14 + x4 = -14 + 14x2 Solving for variable 'x'. Reorder the terms: 14 + 14 + -14x2 + x4 = -14 + 14x2 + 14 + -14x2 Combine like terms: 14 + 14 = 28 28 + -14x2 + x4 = -14 + 14x2 + 14 + -14x2 Reorder the terms: 28 + -14x2 + x4 = -14 + 14 + 14x2 + -14x2 Combine like terms: -14 + 14 = 0 28 + -14x2 + x4 = 0 + 14x2 + -14x2 28 + -14x2 + x4 = 14x2 + -14x2 Combine like terms: 14x2 + -14x2 = 0 28 + -14x2 + x4 = 0 Begin completing the square. Move the constant term to the right: Add '-28' to each side of the equation. 28 + -14x2 + -28 + x4 = 0 + -28 Reorder the terms: 28 + -28 + -14x2 + x4 = 0 + -28 Combine like terms: 28 + -28 = 0 0 + -14x2 + x4 = 0 + -28 -14x2 + x4 = 0 + -28 Combine like terms: 0 + -28 = -28 -14x2 + x4 = -28 The x term is -14x2. Take half its coefficient (-7). Square it (49) and add it to both sides. Add '49' to each side of the equation. -14x2 + 49 + x4 = -28 + 49 Reorder the terms: 49 + -14x2 + x4 = -28 + 49 Combine like terms: -28 + 49 = 21 49 + -14x2 + x4 = 21 Factor a perfect square on the left side: (x2 + -7)(x2 + -7) = 21 Calculate the square root of the right side: 4.582575695 Break this problem into two subproblems by setting (x2 + -7) equal to 4.582575695 and -4.582575695.Subproblem 1
x2 + -7 = 4.582575695 Simplifying x2 + -7 = 4.582575695 Reorder the terms: -7 + x2 = 4.582575695 Solving -7 + x2 = 4.582575695 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + x2 = 4.582575695 + 7 Combine like terms: -7 + 7 = 0 0 + x2 = 4.582575695 + 7 x2 = 4.582575695 + 7 Combine like terms: 4.582575695 + 7 = 11.582575695 x2 = 11.582575695 Simplifying x2 = 11.582575695 Take the square root of each side: x = {-3.403318336, 3.403318336}Subproblem 2
