Simplifying (-9x4 + 5x2 + -7) + -1(-13 + -10x2 + -14x4) = 0 Reorder the terms: (-7 + 5x2 + -9x4) + -1(-13 + -10x2 + -14x4) = 0 Remove parenthesis around (-7 + 5x2 + -9x4) -7 + 5x2 + -9x4 + -1(-13 + -10x2 + -14x4) = 0 -7 + 5x2 + -9x4 + (-13 * -1 + -10x2 * -1 + -14x4 * -1) = 0 -7 + 5x2 + -9x4 + (13 + 10x2 + 14x4) = 0 Reorder the terms: -7 + 13 + 5x2 + 10x2 + -9x4 + 14x4 = 0 Combine like terms: -7 + 13 = 6 6 + 5x2 + 10x2 + -9x4 + 14x4 = 0 Combine like terms: 5x2 + 10x2 = 15x2 6 + 15x2 + -9x4 + 14x4 = 0 Combine like terms: -9x4 + 14x4 = 5x4 6 + 15x2 + 5x4 = 0 Solving 6 + 15x2 + 5x4 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 1.2 + 3x2 + x4 = 0 Move the constant term to the right: Add '-1.2' to each side of the equation. 1.2 + 3x2 + -1.2 + x4 = 0 + -1.2 Reorder the terms: 1.2 + -1.2 + 3x2 + x4 = 0 + -1.2 Combine like terms: 1.2 + -1.2 = 0.0 0.0 + 3x2 + x4 = 0 + -1.2 3x2 + x4 = 0 + -1.2 Combine like terms: 0 + -1.2 = -1.2 3x2 + x4 = -1.2 The x term is 3x2. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x2 + 2.25 + x4 = -1.2 + 2.25 Reorder the terms: 2.25 + 3x2 + x4 = -1.2 + 2.25 Combine like terms: -1.2 + 2.25 = 1.05 2.25 + 3x2 + x4 = 1.05 Factor a perfect square on the left side: (x2 + 1.5)(x2 + 1.5) = 1.05 Calculate the square root of the right side: 1.024695077 Break this problem into two subproblems by setting (x2 + 1.5) equal to 1.024695077 and -1.024695077.Subproblem 1
